Abstract
In a solid-state imaging element provided with a differential pair of transistors, noise of a signal from the differential pair is reduced. The semiconductor integrated circuit includes a pixel circuit and a pair of TFETs (Tunnel Field Effect Transistors). In the semiconductor integrated circuit, the pixel circuit photoelectrically converts incident light to generate a pixel signal. Further, in the semiconductor integrated circuit, the pair of TFETs amplifies the difference between the pixel signal generated by the pixel circuit and a predetermined reference signal that changes with time, and outputs the amplified difference as a differential amplification signal.
