Claim 2:
3. The proximity sensor according to claim 1, wherein the reset circuit comprises a switch capacitor circuit coupled to a reference voltage, wherein the switch capacitor circuit further comprises:
a capacitor, having a first terminal and a second terminal;
a first reset switch, coupled between the first terminal and the integration circuit;
a second reset switch, coupled between the first terminal and a ground terminal;
a third reset switch, coupled between the second terminal and the reference voltage; and
a fourth reset switch, coupled between the second terminal and the ground terminal,
wherein while the first integration signal or the second integration signal is greater than the threshold value, the first reset switch and the third reset switch are turned on, and the second reset switch and the fourth reset switch are turned off, whereby to reset the first integration signal or the second integration signal.
