Abstract
An image capturing device may include a ramp generator circuit that may be used in performance of analog-to-digital conversion of image signals from pixels of an image sensor. The ramp generator circuit may generate a voltage having one or more rising and/or falling portions, using a reference voltage and an integration current. The ramp generator circuit may include a first sample-and-hold switch and/or a second sample-and-hold switch. The ramp generator circuit may selectively turn off the first and/or the second sample-and-hold switches to hold the reference voltage and/or a bias voltage that is used for generating the integration current during analog-to-digital conversion of the image signals. As a result, reference voltage, bias voltage, and/or integration current may be held and substantially stabilized during the analog-to-digital conversion.
