Title :
Operating modes of dynamic-power-supply transmitter amplifiers
Abstract :
Any amplifier operated with a varying power supply is actually a 3-port circuit. When an amplifier is characterized as a 3-port for dynamic power supply operation, three separate operating modes (2 nonlinear, 1 linear) appear: L-mode, C-mode, and P-mode. Each of these modes, along with their relationships and differences, are presented and discussed.
