Abstract
A sensing circuit for an organic light-emitting diode (OLED) driver includes a sample and hold circuit and a clamping circuit. The sample and hold circuit includes a capacitor. The clamping circuit, coupled to the sample and hold circuit, is configured to clamp a sensing voltage received by the sample and hold circuit to conform to a withstand voltage of the capacitor.
