Design of a Readout Scheme for a MEMS Microphone

This design mainly proposes a readout scheme for MEMS microphone with positive feedback to decrease the parasitic capacitance. It is designed in CMOS014 technology with a supply voltage of 3.3 V. The proposed architecture can increase the microphone’s sensitivity with a comparatively low bias voltage. It enables the microphone to achieve high...

Energy-Efficient Capacitive-Sensor Interface Based on A Multi-Slope ADC

This thesis presents an energy-efficient capacitive sensor interface based on a multi-slope analog-to-digital converter (ADC). This highly stable capacitance-to-digital converter (CDC) utilizes precision resistor as reference components. By utilizing a multi-slope analog-to-digital converter, the conversion time of this design is reduced down to...
