Abstract
According to the invention, a system for dynamically scaling bias current on an imaging system is disclosed. In the invention an image sensor capable of producing at least a two-dimensional image and capable of at least two modes of operation is equipped with a control unit. The control unit determines a digital output for each of the modes of operation of the imaging system and outputs the digital outputs to a converter. The converter converts the digital output from the control unit to a bias current and provides this output to an analog and or mixed signal circuit associated with the imaging system that has operating characteristics that may be varied by the application of different bias currents.
