摘要： Disclosed are a pixel, a pixel array, and an image sensor including the pixel array. The pixel includes a first photo-sensing unit to detect a visible light and an IR, and a second photo-sensing unit provided at one side of the first photo-sensing unit to detect a light in which the IR is blocked.

摘要： 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.

摘要： 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.
