Abstract
An apparatus and method for providing a power supply compensated voltage or current is presented. A supply compensated current and voltage source utilizes a differential amplifier connected to a bandgap reference voltage and a scaled power supply voltage. When power supply varies, the differential amplifier regulates a stable compensated output. The output may be a compensated voltage or current. In addition, multiple currents and voltages may be referenced from the differential amplifier. The stable compensated output may be supplied as a reference bias for external circuitry. In addition, the compensated output may be supplied to a voltage controlled oscillator.
