Patent ID: 8466744

Claim:
An amplifier circuit with enhanced amplification linearity, comprising: a driver stage exposing at least an inverting input and a non-inverting input; wherein the driver stage comprises a Complementary Feedback Pair (CFP) at the inverting input and a CFP at the non-inverting input; wherein the driver stage further comprises one or more of a current mirror module, and a constant current module; wherein the inverting input is configured to couple with a first input filter network and with a first feedback network; and wherein the non-inverting input is configured to couple with a second input filter network and with a second feedback network; and a Voltage Amplifier Stage (VAS) coupled to the driver stage, the VAS comprising a different CFP module which is not shared with the driver stage and the VAS exposing at least one VAS output; wherein the at least one VAS output is configured to couple to one or more of a power transistors module, a zobel network and filters module, and an output signal interface; and wherein the amplifier circuit is configurable for use in one or more of a preamplifier or power amplifier circuit.
