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.
Claims13
An electronic device comprising:
- a ramp signal generation circuit configured to generate a ramp signal having a second slope that is decreased by a first level from a first slope which corresponds to an analog gain;
- and
- a slope correction circuit configured to basically increase the second slope of the ramp signal by the first level and optionally increase or decrease a slope of the ramp signal by a second level to obtain the first slope,
- wherein the slope correction circuit includes at least one second resistor part electrically coupled in parallel to an output terminal of the ramp signal, and
- the second resistor part reflects a second resistance value corresponding to the second level in the output terminal on the basis of a second correction code signal.

A method for driving an electronic device comprising:
- intentionally generating a ramp signal having a second slope increased or decreased more than a first slope corresponding to an analog gain;
- basically correcting the ramp signal to have the first slope by enabling at least one of first resistor parts electrically coupled in parallel to an output terminal of the ramp signal;
- and
- optionally correcting the ramp signal to have the first slope when the ramp signal has a third slope increased or decreased more than the first slope by disabling the at least one of first resistor parts or enabling at least one of second resistor parts electrically coupled in parallel to the output terminal of the ramp signal.
