Abstract
Amplitude modulation-phase modulation (AM-PM) linearization in power amplifier techniques are disclosed. In one aspect, a fixed capacitor is placed in parallel to a cascode device within a power amplifier. The sum of capacitances from the cascode device and the parallel capacitor may be relatively fixed across voltage swings, allowing for small phase changes across a wide range of signal amplitudes passing through the power amplifier. The small phase changes across voltage swings make it easier to provide compensation for such phase changes resulting in a more efficient device.
