Abstract :
In this paper, we present a single-ended to differential capacitive sensor interface circuit suitable for implementation in CMOS. The interface circuit converts the capacitance change of a single sensor capacitor into a differential output voltage. The circuit has been designed in a 0.8μm CMOS technology.
