APPARATUS AND METHOD FOR PREVENTING CHARGE PUMPING IN SERIES CONNECTED DIODE STACKS |
摘要 |
An ambient light sensor includes a first stack of at least two photodiodes, wherein a cathode of one of the at least two photodiodes is electrically connected to an anode of another of the at least two photodiodes. The ALS further includes a bias source for providing a bias voltage to the first stack, and at least one switch electrically connected to the first stack. The at least one switch is operative to periodically apply the bias voltage to and remove the bias voltage from the first diode stack.
