Abstract
A clock generation circuit, comprising a first RC circuit, a first switch, a second RC circuit, a second switch, a comparator and a logic circuit. The first RC circuit comprises a first capacitor, coupled to a first predetermined voltage level and a second predetermined voltage level. The second RC circuit comprises a second capacitor, coupled to the first switch. The comparator comprises: a first input terminal, coupled to the second RC circuit and the second switch; a second input terminal, configured to receive a reference voltage level; and an output terminal, coupled to a control terminal of the first switch and a control terminal of the second switch. The logic circuit is coupled to the output terminal of the comparator, configured to generate a clock signal. In one embodiment, the clock generation circuit is applied to an image sensor.
