ABSTRACT:
A method and apparatus are disclosed for adjusting the offset voltage of a circuit. In one embodiment, the method comprises: supplying reference and supply voltages to the circuit, controlling a voltage across a memory element to be approximately equal to the reference voltage, comparing the current through the memory element to a predetermined value, and adjusting an offset voltage of the circuit, where the offset may remain substantially constant despite changes in the supply voltage.
