Abstract: Provided are a converter circuit and a method of driving the same. The converter circuit includes: an input unit receiving a conversion target signal; a detection unit receiving a conversion target signal for each interval from the input unit, sampling the conversion target signal for each interval according to a plurality of timings to calculate an average value for each interval, and outputting a comparison unit input signal by using the average value for each interval; and a comparison unit comparing the comparison unit input signal with a predetermined reference signal to output a comparison result value.

Abstract: A relaxation oscillator and a method for offset cancellation in a relaxation oscillator. The relaxation oscillator comprises two comparator units, each comparator unit comprising a comparator element and a memory element; and a switch control generator coupled to each of the comparator units; wherein each comparator unit, in a reset state, stores an input-offset voltage on the memory element under the control of the switch control generator such that, in a comparison state, the input-offset voltage is applied to both inputs of the comparator for implementing an offset-free threshold.

Abstract: A method for converting a sensor capacitance under parasitic capacitance conditions and a capacitance-to-voltage (CV) converter circuit for converting a sensor capacitance under parasitic capacitance conditions are provided. The method comprises the step of using a two stage operational amplifier (op-amp) in non-unity-gain configuration, wherein the two stage op-amp is chosen to be unstable in unity-gain configuration for reducing power consumption.
