Abstract: ...
The present invention relates to a method and device for measuring dielectrics in fluids, such as water, characterized by a first printed circuit board (PCB), a first conductor on the first side of said first PCB, a second conductor on the second side of said first PCB, a first polymer affinity layer and a second polymer affinity layer on top of the first and second sides of the first PCB respectively, a second PCB equipped with holes and a first conductor plate placed on top of the first affinity layer and a third PCB equipped with holes and a second conductor plate placed on top of the second affinity layer. The result is a sensor consisting of a first PCB sandwiched between the first and second polymer affinity layers and between the second and third PCBs. The sensor is placed in the fluid under investigation and the polymer affinity layers in the sensor absorb chemical compounds and / or ions present in the fluid. At lower frequencies the sensor acts as a capacitive sensor, where absorbed compounds can be characterized by changes in the capacitor value and in the losses. At higher frequencies, the sensor behaves electrically as a stub resonator, the absorbed compounds and / or ions can be characterized or identified through impedance spectroscopy.

Abstract: ...
This paper presents the design aspect of a BJT-based temperature sensor implemented in standard CMOS technology that is optimized for its noise-power performance. The interface electronics of the sensor consists of a continuous-time duty-cycle modulator, where a capacitor is periodically charged and discharged, with two temperature-dependent current sources, between two thresholds determined by a Schmitt trigger. In order to optimize the noise properties of the sensor, the major noise sources have been analyzed and optimized using target specifications of the manufacturer. Experimental results are in agreement with those of simulations and analytical calculations. The sensor has been implemented in 0.7μm CMOS technology. At 3.3V supply, the measured temperature resolution amounts to 3mK for a measurement time of 1.8ms. The test results show that a Resolution Figure of Merit (RFoM) of 3.2pJK² has been achieved in this design, which is the best reported result for BJT-based temperature sensors in the market.

Abstract: ...
Impedance sensors can be defined as being a set of electrodes which can be used to measure electrical properties of materials or structures. Once these properties are known, it appears that the features of measurements performed with such sensors depend for a large part on the properties of the material or structure to be characterized and only partly on the characteristics of the electrodes. The electrical properties of the sensor in its application can be modeled with passive elements in equivalent electrical circuits. The challenging task for the designer is to make such a sensor system sensitive for the measurands and to obtain immunity for other parameters. In this chapter, we consider impedance sensors to be sensors in a certain measurement environment, and that in the electric model presentation of this setup there is at least one resistive or one reactive component of interest which has to be measured.

A Low-Power CMOS Smart Temperature Sensor with a Batch-Calibrated Inaccuracy of ±0.25°C (±3σ) from -70°C to 130°C

Volume 13, Issue 5, pp. 1840‒1848, May 2013. DOI: 10.1109/JSEN.2013.2244033

Abstract: ...
In this paper, a low-power CMOS smart temperature sensor is presented. The temperature information extracted using substrate PNP transistors is digitized with a resolution of 0.03°C using a precision switched-capacitor (SC) incremental ΔΣ A/D converter. After batch calibration, an inaccuracy of ±0.25°C (±3) from -70°C to 130°C is obtained. This represents a two-fold improvement compared to the state-of-the-art. After individual calibration at room temperature, an inaccuracy better than ±0.1°C over the military temperature range is obtained, which is in-line with the state-of-the-art. This performance is achieved at a power consumption of 65 μW during a measurement time of 100 ms, by optimizing the power/inaccuracy tradeoffs, and by employing a clock frequency proportional to absolute temperature. The latter ensures accurate settling of the SC input stage at low temperatures, and reduces the effects of leakage currents at high temperatures.

An energy-efficient 15-bit capacitive-sensor interface based on period modulation

Volume 47, Issue 7, pp. 1703‒1711, July 2012. DOI: 10.1109/jssc.2012.2191212

Abstract: ...
This paper presents an energy-efficient capacitive-sensor interface with a period-modulated output signal. This interface converts the sensor capacitance to a time interval, which can be easily digitized by a simple digital counter. It is based on a relaxation oscillator consisting of an integrator and a comparator. To enable the use of a current-efficient telescopic OTA in the integrator, negative feedback loops are applied to limit the integrator's output swing. To obtain an accurate ratiometric output signal, auto-calibration is applied. This eliminates errors due to comparator delay, thus enabling the use of a low-power comparator. Based on an analysis of the stability of the negative feedback loops, it is shown how the current consumption of the interface can be traded for its ability to handle parasitic capacitors. A prototype fabricated in 0.35 μm standard CMOS technology can handle parasitic capacitors up to five times larger than the sensor capacitance. Experimental results show that it achieves 15-bit resolution and 12-bit linearity within a measurement time of 7.6 ms for sensor capacitances up to 6.8 pF, while consuming only 64 μA from a 3.3 V power supply. Compared to prior work with similar performance, this represents a significant improvement in energy efficiency.

Abstract: ...
There is a clear clinical need for creating 3-D images of the heart. One promising technique is the use of transesophageal echocardiography (TEE). To enable 3-D TEE, we are developing a miniature ultrasound probe containing a matrix piezoelectric transducer with more than 2000 elements. Because a gastroscopic tube cannot accommodate the cables needed to connect all transducer elements directly to an imaging system, a major challenge is to locally reduce the number of channels, while maintaining a sufficient signal-to-noise ratio. This can be achieved by using front-end receiver electronics bonded to the transducers to provide appropriate signal conditioning in the tip of the probe. This paper presents the design of such electronics, realizing time-gain compensation (TGC) and micro-beamforming using simple, low-power circuits. Prototypes of TGC amplifiers and micro-beamforming cells have been fabricated in 0.35-μm CMOS technology. These prototype chips have been combined on a printed circuit board (PCB) to form an ultrasound-receiver system capable of reading and combining the signals of three transducer elements. Experimental results show that this design is a suitable candidate for 3-D TEE.

Abstract: ...
This paper presents a 9-channel low-power receiver ASIC dedicated to a matrix piezoelectric ultrasound transducer for 3D Trans-Esophageal Echocardiography (TEE). It consists of 9 low-noise amplifiers (LNAs), 9 time-gain-compensation (TGC) amplifiers and a 9:1 micro-beamformer. A prototype ASIC has been implemented in 0.35 μm CMOS technology, with a core area of 0.98 mm × 1.7 mm. It is operated at a 3.3 V supply and consumes only 0.5 mW per channel. The measured channel-to-channel mismatch is within ±1 dB. Acoustic measurements proved the micro-beamforming function of the ASIC when processing real ultrasound signals from a 3 × 3 transducer array. These promising results show that this design, after layout optimization, is suitable to be scaled up to accommodate a full matrix transducer.

Electronics Letters,
Volume 47, Issue 18, pp. 1011‒1012, September 2011. DOI: 10.1049/el.2011.1786

Abstract: ...
The proposed ultrasound beamformer is based on the delay-and-sum beamforming principle. The circuit consists of several programmable delay lines. Each delay line is constructed by pipeline-operated sample-and-hold (S/H) stages with digitally-assisted delay control, which ensure delay-independent gain and good timing accuracy. The summation is realised in the charge domain using the charge-averaging method, which consumes virtually no extra die area or power. A prototype beamformer has been fabricated in a 0.35 m CMOS process to interface nine transducer elements. Measurement results show that this circuit consumes much less power and chip area than the prior art, while maintaining good accuracy and flexibility.

Abstract: ...
In this paper, a programmable time-gain compensation amplifier dedicated to a 2D piezoelectric ultrasound transducer is presented. It uses an open-loop amplifier structure consisting of a voltage-to-current converter and a current-to-voltage converter. The circuit has been designed in a standard 0.35-μm CMOS process. Simulation and measurement results show that gains of 0dB, 12dB, 26dB and 40dB can be achieved for input signals centered at 6MHz with 80dB dynamic range (100μV to 1V). The measured gain errors at 6MHz are below 1dB for all gain settings. The amplifier consumes only 130μW when driving a 250fF load.

Abstract: ...
This paper analyzes the nonidealities of temperature sensors based on substrate pnp transistors and shows how their influence can be minimized. It focuses on temperature measurement using the difference between the base-emitter voltages of a transistor operated at two current densities. This difference is proportional to absolute temperature (PTAT). The effects of series resistance, current-gain variation, high-level injection, and the Early effect on the accuracy of this PTAT voltage are discussed. The results of measurements made on substrate pnp transistors in a standard 0.5μm CMOS process are presented to illustrate the effects of these nonidealities. It is shown that the modeling of the PTAT voltage can be improved by taking the temperature dependency of the effective emission coefficient into account using the reverse Early effect. With this refinement, the temperature can be extracted from the measurement data with an absolute accuracy of ±0.1°C in the range of -50 to 130°C.
