A Capacitive-to-Digital Converter With Automatic Range Adaptation for Readout Instrumentation

Abstract

Capacitive sensors have profoundly found their way in everyday life. Devices and instrumentation ranging from specialty equipment to smartphones all employ in one way or the other a capacitive sensor and its associated readout circuit, making the latter ubiquitious. We present a capacitive readout system that automatically adapts its range to the unknown… (More)
