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.

摘要： A solid-state imaging device includes an A/D converter per column. The A/D converter performs a first A/D conversion that (i) refines, using a first comparator, a range including a potential of an analog signal to a range of a potential corresponding to a difference between a first potential and a second potential through a binary search, and further (ii) generates, based on a result of the binary search, a first digital signal being a high-order portion of a digital signal. The A/D converter also performs a second A/D conversion that generates, based on a ramp signal and the result of the binary search, a second digital signal being a low-order portion of a remainder of the digital signal, by measuring a time necessary for an output of a second comparator to be inverted.
