Abstract
Provided is an electronic device including a ramp signal generation circuit configured to generate a ramp signal having a second slope that is greater by a first level than a first slope which corresponds to an analog gain, and a slope correction circuit configured to correct the second slope of the ramp signal by the first level to obtain the first slope.
Claims20
An electronic device comprising:
- a ramp signal generation circuit configured to generate a ramp signal having a second slope that is greater by a first level than a first slope which corresponds to an analog gain;
- and
- a slope correction circuit configured to correct the second slope of the ramp signal by the first level to obtain the first slope.
An electronic device comprising:
- a ramp signal generation block configured to generate a ramp signal on a basis of a ramp code signal;
- a slope adjustment block configured to adjust a slope of the ramp signal such that the ramp signal has a second slope more than a first slope corresponding to an analog gain, on a basis of a gain code signal, the second slope corresponding to adjusting the first slope by the first level;
- a first slope correction block configured to basically correct the slope of the ramp signal by the first level on a basis of a first correction code signal;
- and
- a second slope correction block configured to secondarily correct the slope of the ramp signal by a second level on a basis of a second correction code signal.
