Abstract
A circuit includes a pixel structure having a photo sensitive element and a read transistor. The read transistor includes a first load path terminal coupled to the photo sensitive element, and a second load path terminal coupled to a voltage bus. The circuit also includes a first transistor having a third load path terminal coupled to a power supply node, and a fourth load path terminal configured to be coupled to a current source. The circuit further includes a first control switch coupled between the voltage bus and the fourth load path terminal of the first transistor.
