A low voltage differential op amp with novel common mode feedback

A new low voltage differential amplifier featuring a novel common mode feedback structure (CMFB) is presented. It provides rail-to-rail common and differential mode input range by the use of a nMOS depletion input pair transistors that can easily be processed in standard CMOS technologies.
