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.

Abstract: Calibrating of A/D converters is carried out by obtaining adjustable reference voltages which are used in in A/D conversion, comparing a first divided reference voltage of a full range voltage Vref, with a second divided reference voltage of Vref using analog to digital converters that are used in the A/D conversion; and adjusting at least one of said reference voltages to obtain a set ratio between said multiple ones of said reference voltages. The compared values can include a divided version of Vref, e.g., 3/8 Vref.

The mesh may be provided for ground and power and/or both. The mesh may be on different layers, so that one portion of the mesh is exactly over the other portion of the mesh. The mesh takes up a portion of real estate on the chip in between the individual photoreceptors, in locations where image sensing parts cannot be located. In an embodiment, the mesh can be intentionally broken at various locations to optimize the path length.
