ABSTRACT:
A differential amplifier is configured to receive an input signal whose magnitude is referenced between a reference voltage and a first power supply magnitude. A differential current conducted by the differential amplifier induces current to be conducted by a first current mirror, which in turn induces current to be conducted by a second current mirror. The current conducted by the second current mirror produces an output signal that is referenced between the reference voltage and a second power supply magnitude.
