POWER SUPPLY DEPENDENT VOLTAGE REFERENCE CIRCUIT

A circuit adapted for use in comparing voltages in a manner that is insensitive to power supply variations includes a pair of reference cells controlling the reference voltage of a sense amplifier through control of a pair of reference transistors and an input circuit for conditioning data having a matched input pair of transistors, so that input data will control the voltage on the input terminal of a sense amplifier in a manner such that both inputs to the sense amp track voltage, thermal and processing variations.
