DRIVER CIRCUIT, DRIVING METHOD, ACTIVE PIXEL SENSOR, IMAGE SENSOR, AND ELECTRONIC DEVICE

WIPO Patent Application WO/2018/082563

A1

A driver circuit, a driving method, an active pixel sensor, an image sensor, and an electronic device. The driver circuit comprises a reset circuit (1), a photoelectric sensing circuit (2), a signal forming circuit (3), a signal conversion circuit (4), and a signal output circuit (5). The reset circuit (1) resets the photoelectric sensing circuit (2) and the signal forming circuit (3). The photoelectric sensing circuit (2) performs photoelectric conversion on incident light radiation to a photoelectric voltage signal. The signal forming circuit (3) transmits the photoelectric voltage signal to the signal conversion circuit (4), and transmits a compensated photoelectric voltage signal to the signal conversion circuit (4). The signal output circuit (5) transmits a second voltage to the signal conversion circuit (4) and the signal forming circuit (3), and outputs a photoelectric current signal. The signal conversion circuit (4) forms the compensated photoelectric voltage signal and outputs the photoelectric current signal to the signal output circuit (5). The driver circuit can avoid the problem of image distortion in a captured picture.
