摘要: A high voltage drive circuit includes an edge detector for generating an edge detection signal by detecting edges of a first high side input signal and a first low side input signal, the edge detector providing a high side delay signal and a low side delay signal by delaying the first high side input signal and the first low side input signal, a dead time generator for generating a dead time signal indicating a preset dead time in response to the edge detection signal, and a driver comprising a drive signal generator for providing a high side output signal and a low side output signal by inserting the preset dead time based on the dead time signal into the high side delay signal and the low side delay signal.

摘要: A CMOS image sensor includes a photodiode, a switch configured to transfer a signal sensed by the photodiode to a sensing node, and a comparator electrically and directly connected to the sensing node and configured to compare the sensed signal of the sensing node and a ramp signal. Reset offset of the comparator is maintained at a constant offset voltage level during an initialization mode.
