초록
For high-accuracy signal processing of differential capacitance transducers, an interface circuitry based on a switched-capacitor sample/hold circuit is developed. Driven by nonoverlapping two-phase clocks, the interface produces the output voltage which is proportional to the ratio of difference-to-sum of two capacitors of a differential transducer.
