Energy-efficient capacitive-sensor interface based on an incremental Delta-Sigma modulator employing current-starved inverter-based OTAs

An interface circuit for a fully-integrated capacitive humidity-sensor is implemented using 0.16?m standard CMOS technology. This interface circuit is intended to be used in a smart RFID sensor platform. This thesis focuses on improving the energy-efficiency of the interface circuit. A third-order incremental delta-sigma converter based on...
