Abstract: Receiver circuits and methods of processing received signals are disclosed herein. An embodiment of a receiver circuit includes a differential input having a first input and a second input and a differential output having a first output and a second output. A first feedback loop is connected to the input and the output, wherein the first feedback loop centers a differential output voltage around a common mode output voltage so that the differential sum is zero centered on the common mode output voltage. The circuit also includes a second feedback loop, wherein the second feedback loop centers the voltage at the first input and the voltage at the second input to a reference voltage.

Abstract: Amplifier circuits and methods of cancelling the Miller effects in amplifiers are disclosed herein. An embodiment of an amplifier circuit includes an input and an output. An amplifier is connected between the input and the output of the circuit. A voltage source is connected to the output, wherein the voltage source output is one hundred eighty degrees out of phase with the voltage output by the amplifier, and wherein the voltage source cancels gain due to the Miller effect of a Miller capacitance between the input and output.
