چکیده

A new readout imaging system with enhanced dynamic range (DR) and low power consumption is presented. The DR is enhanced by using feedback to control the integration time of the sensor. The feedback is implemented within an in-pixel-level ADC. The power consumption is reduced by switching the bias circuit off when it is not needed for the system, this readout circuit is used for a hybrid sensor: the photodiode and the readout circuits are placed in two different layers, the interconnections are made through bond pads.
