ABSTRACT:
A reset voltage generator for CMOS imagers is disclosed. The voltage generator contains a “top” voltage generator and a “bottom” voltage generator, both of which are switched in and out of operation. A predetermined reset voltage is thereby generated independent of the power supply voltage (e.g., Vdd) and independent of any noise and/or voltage shifts associated with the power supply voltage.
