Analysis and elimination of hysteresis and noisy precursors in power amplifiers [PDF]
, 2006 Power amplifiers (PAs) often exhibit instabilities leading to frequency division by two or oscillations at incommensurate frequencies. This undesired behavior can be detected through a large-signal stability analysis of the solution.

Variable-Voltage Class-E Power Amplifiers [PDF]
2007 IEEE/MTT-S International Microwave Symposium, 2007 Abstract—The Class-E power amplifier is widely used due to its high efficiency, resulting from switching at zero voltage and zero slope of the switch voltage. In this paper, we extend general analytical solutions for the Class-E power amplifier to the ideal single-ended Variable-Voltage Class-E (Class-EV V ) power amplifier that switches at zero slope ...
