Abstract
A pixel circuit and method for operating the same is disclosed. The circuit includes a first driver circuit coupled to receive an analog pixel data, transfer signal and reset signal. The circuit further includes a source follower transistor having a source terminal coupled to a column node, and a gate terminal coupled to the first driver circuit. The circuit further includes a second driver circuit coupled to receive the transfer signal and the reset signal. The second driver circuit is capacitively coupled to the column node through a first capacitor.
