Abstract
A new inverter-based fully-differential amplifier is provided including one or more common-mode feedback transistors coupled to each inverter, which transistors operate in the liner region. Accordingly, due to the fully-differential nature of the new inverter-based fully-differential amplifier, the amplifier provides an improved Power Supply Rejection Ratio (PSRR), provides a reduced sensitivity to supply voltage and process or part variations, and does not require an auto-zeroing technique to be utilized, which ultimately saves power, all while utilizing the low-voltage and low-power advantages of an inverter-based design.
