Claim 16:
17. An image sensor, comprising:
a pixel array comprising a plurality of pixel circuits arranged in a matrix, each of the pixel circuits comprising:
an avalanche diode having an anode and a cathode, the cathode being connected to a positive bias voltage;
a first transistor, a gate of the first transistor connected to the anode of the avalanche diode, and a source of the first transistor connected to a ground voltage; and
a second transistor, a gate of the second transistor configured to receive an exposure signal, a source of the second transistor connected to a drain of the first transistor, and a drain of the second transistor configured to generate an output voltage; and

a plurality of readout lines each being coupled to the drain of the second transistor of each pixel circuit of one pixel circuit column to output the output voltage.
