The following paper presents the charge-control analysis of operation of the transistor as a switch in the inverter circuit in which the collector current is constant while the transistor is saturated. This paper presents the charge-control analysis of the class E high-efficiency switching-mode tuned power amplifier with only 1 inductor and 1 capacitor in the load network, along with experimental results. In this amplifier, the collector current increases linearly with time while the transistor is saturated. We assume linear charge parameters of the transistor, and rectangular-wave base-drive current. The following are determined: the waveforms of all components of the base current and the base stored charge, the switching times, the driving power, and the power gain. A new definition of the overdrive factor of the transistor is introduced and the condition of the transistor saturation is discussed. It is shown that the base current necessary to drive the transistor to the edge of saturation increases with frequencyfforf > f_{beta}.
