Abstract

Disclosed is an amplifier circuit including a first input terminal that receives a ramp signal, a second input terminal that receives a pixel signal, an output terminal that outputs an output signal, wherein the output signal is based on comparing the pixel signal and the ramp signal, a capacitor that is electrically connected between the output terminal and a ground terminal, a switch that is electrically connected with the capacitor, and a current source that outputs a power current. The pixel signal corresponds to a first conversion gain or a second conversion gain, and a value of the second conversion gain is higher than a value of the first conversion gain, and a bandwidth of the amplifier circuit is adjusted depending on whether the pixel signal corresponds to the first conversion gain or the second conversion gain.
