Abstract: A simple and cost-effective resonance-based method for capacitance measurement is presented. The proposed method utilizes voltage measurement using the internal analog-to-digital converter ...

Abstract: This paper presents an absolute capacitive rotary encoder using a sample-and-hold demodulator (SHD) to reduce interference between sine and cosine channels. The capacitive encoder measures ...
