Abstract
A device is disclosed that includes a first gain stage and a first amplifier. The first gain stage is configured to generate a first signal according to a first input signal, and to multiply the first signal and the first input signal, to generate a second signal at a first output terminal, in which the first signal is associated with the even order signal components of the first input signal. The first amplifier is configured to amplify the first input signal to generate a third signal at the first output terminal, in order to output a first output signal with the first gain stage, in which the first output signal is the sum of the second signal and the third signal.

A circuit, comprising:
- a first gain stage configured to remove odd order components associated with a first input signal in order to generate a first signal according to the first input signal, and configured to multiply the first signal and the first input signal, to generate a second signal at a first output terminal, wherein the first signal is associated with even order signal components of the first input signal;
- and
- a first amplifier configured to amplify the first input signal to generate a third signal at the first output terminal, in order to output a first output signal with the first gain stage, wherein the first output signal is the sum of the second signal and the third signal.
A circuit, comprising:
- an odd order remover configured to operate as a square current generator in order to generate a first signal according to a first input signal, wherein the first signal is associated with even order signal components in the first input signal;
- and
- a multiplier configured to multiply the first input signal and the first signal, to generate a second signal at a first output terminal.
A method, comprising:
- generating, by an odd order remover configured to operate as a square current generator, a first signal according to a first input signal;
- and
