High-Speed Interfaces for Capacitive Displacement Sensor

Sha Xia

This thesis describes the theory, design, and implementation of high-speed capacitive displacement sensor interface circuits. The intended application is to readout the capacitive displacement sensor used in a servo loop, where the measurement time needs to be low to ensure loop stability. The work employs baseline-capacitance cancellation technique to reach a high energy-efficiency and high conversion speed.
