Patent ID: 8723603

Claim:
An amplifier comprising: a first input terminal; a second input terminal; an input stage comprising a first input and a second input, the second input electrically connected to the second input terminal, the input stage configured to generate a first current at a first current output, the input stage configured to generate a second current at a second current output, and the input stage configured to generate a first voltage feedback signal at a voltage feedback output, the first voltage feedback signal indicative of a voltage level of the second input terminal, wherein the second input of the input stage is configured to receive a current feedback signal, and wherein the first and second currents change in response to the current feedback signal, wherein the voltage feedback output is not a same node as the second input; and a voltage feedback circuit including a first input electrically connected to the first input terminal, a second input configured to receive the first voltage feedback signal, and an output electrically connected to the first input of the input stage, wherein the voltage feedback circuit is configured to control the voltage level of the second input terminal based on the voltage level of the first input terminal.
