A VCII-Based Stray Insensitive Analog Interface for Differential Capacitance Sensors

A VCII-Based Stray Insensitive Analog Interface for Differential Capacitance Sensors

In this paper, a novel approach to implement a stray insensitive CMOS interface for differential capacitive sensors is presented. The proposed circuit employs, for the first time, second-generation voltage conveyors (VCIIs) and produces an output voltage proportional to differential capacitor change...
