Claim 5:
6. The optical sensor of claim 5, wherein a first cathode of the first photodetector is coupled to a first voltage supply node, wherein the optical sensor further comprises:
a first pull down circuit coupled between a first anode of the first photodetector and a first reference voltage node, wherein when enabled, the first pull down circuit couples the first anode of the first photodetector to the first reference voltage node; and
a first pull up circuit coupled between the first anode of the first photodetector and a second voltage supply node, wherein when enabled, the first pull up circuit couples the first anode of the first photodetector to the second voltage supply node.
