Abstract
A low power differential amplifier powered by a plurality of unequal power supply voltages. The input stage operates at a higher power supply voltage so as to maintain its transistors in operational states of saturation while providing a sufficient dynamic signal voltage range. The output stage operates at a lower power supply voltage while providing a sufficient dynamic signal current range.
