Patent number: 8023020Abstract: A photodetecting circuit is disclosed. The photodetecting circuit includes a photodetector, a storage node with first and second node terminals, a transfer transistor disposed intermediate the first node terminal of the storage node and the photodetector for electrically connecting the first node terminal and the photodetector upon receiving a transfer signal to a gate of the transfer transistor, a reset transistor disposed intermediate a reset voltage node and the first node terminal of the storage node for electrically connecting the first node terminal to the reset voltage node upon receiving a reset signal to a gate of the reset transistor, and an output circuit for generating an output signal based on a voltage at the first terminal. First the reset signal is applied, followed by the transfer signal. Next, a compensation signal is applied at the second terminal of the storage node. The compensation signal increases the voltage at the first terminal whilst the output circuit generates the output signal.Type: GrantFiled: July 12, 2010Date of Patent: September 20, 2011Assignee: Silverbrook Research Pty Ltd.Inventors: Alireza Moini, Kia Silverbrook, Paul Lapstun, Peter Charles Boyd Henderson, Zhenya Alexander Yourlo, Matthew John Underwood, Nicholas Damon Ridley
