Classification: CPC H  G | IPC G  H

Claim 0:
1. A circuit, comprising:
a first switching unit and a second switching unit configured to be alternately turned on in response to, respectively, a first control signal and a second control signal that have different voltage levels, wherein first terminals of the first and second switching units are coupled to each other at a first node;
a sensing unit configured to generate a sensing voltage, in response to light, at the first terminals of the first and second switching units;
a first capacitive unit configured to generate a first voltage to a second terminal of the first switching unit, in response to the sensing voltage, at a second node different from the first node;
a second capacitive unit configured to generate a second voltage, in response to the generating the sensing voltage, at a second terminal of the second switching unit; and
a third switching unit coupled between the second node and a third node different from the first and second nodes, wherein the third switching unit is configured to be turned on to increase a voltage level of the third node according to the first voltage for generating a data signal.
