ABSTRACT:
A pixel bias current supply for supplying a stable source of bias current to pixels of an imager includes a current bypass feature for improving stability when one or more pixels of an imager saturates. The pixel bias current supply also features voltage limiters to restrict the output voltage of a pixel in order to prevent reverse video from being output when very strong light is incident upon one or more pixels.
