Abstract:
A circuit for an image sensor pixel receives photogenerated information from an image sensor, such as infrared sensor. The circuit includes a single ended operational amplifier, they can have a simple circuit such as for example 4 transistors. An additional transistor is used in the pixel to regulate the voltage that is used to drive the operational amplifier, to maintain that voltage relative to a bias level. This prevents voltage fluctuations, which would otherwise be passed to the pixel output.
