Low-Power Resistive Bridge Readout Circuit Integrated in Two Millimeter-Scale Pressure-Sensing Systeosystems. By heavily duty-cycling an excitation voltage for the bridge sensor, 6000× less excitation power is consumed compared with conventional DC biasing. The excitation voltage is sampled and used to generate an ADC reference voltage to avoid line voltage fluctuation. The BDC achieves 49.2?dB SN

Advanced Capacitive Sensing for Mobile Devicesfrom the pF range down to aF. Examples to illustrate this include “single-pixel” buttons, sliders, touch screens, and “kilo-pixel” fingerprint readers..Challenges and solutions for sensors, architectures, algorithms, and circuit technology are discussed.

MEMS Microphones: Concept and Design for Mobile ApplicationsMoreover, product specifications are pushing toward contradicting directions—increase of Signal-to-Noise Ratio (SNR) and Acoustic Overload Point (AOP)—with a continuous miniaturization of the package and power savings. To achieve those targets, the development of both the sensor and the readout circ

Both sensors employ a suspended hot-wire transducer to detect the CO.-dependent thermal conductivity (TC) of the ambient air. The resistive transducer is realized in the VIA layer of a standard CMOS process using a single etch step. The first sensor deter

Time of Flight Imaging and Sensing for Mobile Applications This chapter provides an overview of the challenges in TCSPC sensor design for mobile applications. We describe the design of a proof-of-concept TCSPC optical sensor with 10 GS/s conversion rate folded flash time to digital converter (TDC) and on-chip histogram generation, designed to minimize time
