Solid-state imaging device and imaging apparatus including an adjusting circuit that reduces an amplitude of a control signal from a control unit

摘要

A solid-state imaging device includes: a pixel unit which includes a plurality of pixels arranged in rows and columns and which generates pixel signals according to an amount of incident light; a column analog-to-digital converter (ADC) which is disposed for each of the columns of the pixel unit and which performs digital conversion on each of the pixel signals output from the pixels in the column; a timing control unit which generates a control signal for controlling the digital conversion performed by the column ADC; and a logic swing and delay adjusting circuit which is disposed in a signal path for supplying the control signal from the timing control unit to the column ADC and which at least either reduces an amplitude of the control signal or delays the control signal.
