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.
