摘要: A system and method for canceling dark photocurrent in a color sensor circuit is disclosed. described including circuit, differential amplifier circuit. The receives from component of light input. outputs first voltage indicating intensity the component. second an offset voltage. coupled to voltages final output that cancels contributions due photocurrent.
