Abstract
Embodiments of the invention may provide systems and methods for minimizing phase deviation and/or amplitude modulation (AM)-to-phase modulation (PM) conversion for dynamic range, radio frequency (RF) non-linear amplifiers. In order to provide high dynamic range with reduced phase error, embodiments of the invention may utilize two separate paths for processing a signal. In particular, an input signal may be sampled and divided into each path. The first signal path may be used to shape a signal, and in particular, a voltage waveform at the load. The second signal path may be used for generating negative capacitances corresponding to the voltage waveform at the load. By combining the two signals at the load, a high-dynamic range, high-frequency, non-linear amplifier can be achieved that reduces phase error resulting from amplitude fluctuations with a relatively low unity-gain frequency (f) process.
