Abstract:
A circuit and apparatus for filtering harmful harmonics is disclosed. The circuit and apparatus include a power amplifier core that uses equally sized inverter based amplifiers. The amplifier core cells provide uniform load to all phases of a fundamental frequency to cancel all harmonics at an output. The power amplifier stages are driven into nonlinearity, and the combination of harmonics is performed at the output by varying series connected capacitors. The harmonic combination is performed at the output, leaving no further scope of nonlinearity in the signal chain.

Claim (Index 27):
A method, comprising:\n providing a frequency oscillator for generating a signal frequency; providing a frequency divider coupled to the frequency oscillator and configured to divide the signal frequency to generate a plurality of equally spaced phases of the signal frequency; providing a plurality of power amplifiers coupled to the frequency divider and configured to receive the plurality of phases of the signal frequency, amplify signal at the signal frequency and provide a uniform load to each one of the harmonics of the signal frequency, wherein one or more of the frequency oscillator and the frequency divider are programmable to generate a plurality of signal frequencies and a plurality of phases at a fundamental frequency of the signal frequency respectively.
