摘要: A photodetecting circuit is disclosed which includes a photodetector for generating a signal in response to incident light, astorage node, transfer and reset transistors and an output circuit. The storage node has first and second node terminals. The second node terminal is connected to a compensation signal during a read period of the photodetection circuit. The transfer transistor is disposed intermediate the first node terminal of the storage node and the photodetector and is for electrically connecting the first node terminal and the photodetector during an integration period upon receiving a transfer signal to a gate of the transfer transistor, allowing charge stored in the storage node to change based on the signal of the photodetector. The reset transistor has a control node for receiving a reset signal, a first terminal for receiving a reset voltage, and a second terminal electrically connected to the first node terminal, such that the reset voltage is supplied to the first node terminal when the reset signal is asserted at a gate of the reset transistor. The output circuit generates an output signal during the read period of the photodetecting circuit. The output signal is at least partially based on a voltage at the first terminal. The compensation signal is a logically negated version of the transfer signal.
