Claim 0:
1. An image sensor comprising:
a row driver configured to generate a plurality of driving signals;
a plurality of pixels arranged in a first direction in a pixel area and each pixel including a photodiode and a plurality of pixel transistors each configured to receive a corresponding driving signal of the plurality of driving signals; and
a first monitoring circuit located on a first side of the pixel area, including a first transistor and a second transistor connected to each other in series between a power voltage and a first monitoring line, the first transistor and the second transistor being configured to receive a first driving signal and a second driving signal respectively and to generate a first monitoring signal on the first monitoring line,
wherein the plurality of driving signals are applied along the first direction and include the first driving signal and the second driving signal,
wherein the first transistor and the second transistor do a logic AND operation of the first driving signal and the second driving signal to generate the first monitoring signal, and
wherein a drain of the first transistor is connected to a source of the second transistor.
