Abstract
An optical sensor circuit includes a capacitor, a first transistor, a second transistor, a third transistor, a fourth transistor, and a fifth transistor. The capacitor includes a first terminal and a second terminal. Each transistor includes a first terminal, a control terminal, and a second terminal. The second terminal of the capacitor is coupled to a reference voltage terminal. The first terminals of the third transistor and the fourth transistor are coupled to a first voltage terminal. The second terminal of the fifth transistor is coupled to a readout line.
