Abstract
A capacitance of a first line which transmits a ramp signal having a potential changed by a first changing amount is controlled to be larger than a capacitance of a second line which transmits a ramp signal having a potential changed by a second changing amount which is larger than the first changing amount.
Claims26
An apparatus, comprising:
- a supply unit configured to supply a first ramp signal having a potential changed by a first changing amount per unit time and a second ramp signal having a potential changed by a second changing amount which is larger than the first changing amount per unit time;
- a first line configured to transmit the first ramp signal;
- a second line configured to transmit the second ramp signal;
- and
- analog/digital conversion units each of which is configured to be connected to the first and second lines, include a selection unit which outputs one of the first and second ramp signals and a comparison unit which performs a first comparison between the ramp signal output from the selection unit and an analog signal, and obtain a digital signal corresponding to the analog signal by the first comparison,
- wherein a first capacitance of an electric path extending from the supply unit through the first line to the selection unit is larger than a second capacitance of an electric path extending from the supply unit through the second line to the selection unit.

- a first line configured to transmit the first ramp signal;
- a second line configured to transmit the second ramp signal;
- a first analog/digital conversion unit configured to have a first comparison unit which is connected to the first line and cause the first comparison unit to perform a first comparison between the first ramp signal and an analog signal so as to obtain a digital signal corresponding to the analog signal, and
- a second analog/digital conversion unit configured to have a second comparison unit which is connected to the second line and cause the second comparison unit to perform a second comparison between the second ramp signal and the analog signal used in the first comparison so as to obtain a digital signal corresponding to the analog signal,
- wherein a first capacitance of an electric path extending from the supply unit through the first line to the first comparison unit is larger than a second capacitance of an electric path extending from the supply unit through the second line to the first comparison unit.
