Abstract
A new Switched Capacitor (SC) Capacitance-to-Digital Converter (CDC) is presented in this paper. Its output exhibits a high-level of insensitivity to interference, by virtue of the conversion mechanism itself. The proposed scheme is a combination of an SC relaxation oscillator and an integrating type analog-to-digital converter (ADC). Its conversion time is independent of the measurand and hence can be set, such that it is an integral multiple of the interference period, unlike in a dual-slope A...
