Abstract
Provided are a signal readout circuit and a method therefor. In the signal readout circuit, a readout row selector is configured to gate a row of pixel units in a pixel array. A reset row selector is configured to gate first reset switches of the row of pixel units. Each pixel unit in the row in a pixel subarray included in the pixel array converts an optical signal into an electrical signal, and outputs the electrical signal to a connected pixel subarray readout feedback circuit. When it is determined based on the electrical signal that a signal generation condition is met, a reset signal is generated and sent to a first pixel unit, and an output signal is generated for output.
