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 21):
A method, comprising:\n providing a frequency oscillator for generating a fundamental signal frequency; providing a frequency divider coupled to the frequency oscillator and configured to divide the fundamental signal frequency to generate one or more phases of the fundamental signal frequency; providing a power amplifier coupled to the frequency divider, respective amplifier stages of the power amplifier configured to receive the fundamental signal frequency and the one or more phases, the power amplifier comprising:\n one or more buffers configured to buffer one or more of the fundamental signal frequency and the harmonic frequencies; and \n one or more digital-to-analog converters (DAC) coupled to the one or more buffers and configured to combine the fundamental signal frequency and the one or more phases of the fundamental signal frequency.
