Abstract
Provided is a solid state imaging device including a plurality of pixels, a signal line on which a pixel signal is transmitted, a load transistor having a drain connected to the signal line, a readout circuit that reads out the pixel signal from the signal line, and a control unit that controls a current flowing in the load transistor in accordance with a potential of a control terminal. When a reference potential of the pixel fluctuates relatively to a reference potential of the readout circuit, a potential of the control terminal relative to a potential of a source of the load transistor is changed in a same phase with a fluctuation of the reference potential of the pixel.
