Abstract
A photodetecting circuit comprising a photodetector for generating a signal in response to incident light; a storage node having first and second node terminals, the first node terminal being connected to the photodetector to receive the signal such that charge stored in the node changes during an integration period of the photodetecting circuit; and an output circuit for generating an output signal during a read period of the photodetecting circuit, the output signal being at least partially based on a voltage at the first terminal; the photodetecting circuit being configured to receive a reset signal; integrate charge in the storage node during an integration period following receipt of the reset signal; and receive a compensation signal at the second terminal of the storage node at least during the read period, the compensation signal increasing the voltage at the first terminal whilst the output circuit generates the output signal.
