Abstract
A pixel circuit is provided for use in an image sensor. The pixel circuit includes a photosensitive element configured to generate a current signal in response to brightness of light impinging on the photosensitive element, and a converter configured to receive the current signal from the photosensitive element and generate a voltage signal based on the received current signal. The pixel circuit also includes a capacitor electrically coupled to the converter in series and configured to receive the voltage signal from the converter, and an amplifier electrically coupled, at an input, to the capacitor in series and configured to generate, at an output, an amplified signal based on an output signal from the capacitor, wherein there is no feedback between the output and the input of the amplifier. Further, the pixel circuit includes a reset device configured to reset the amplifier in response to a trigger signal being generated.
