Switching waveform prediction of a simple transistor inverter circuit

This paper presents a brief review of charge control equations for base step current drive transistor switching in the grounded emitter configuration. On the basis of these equations, transient switching waveforms are calculated by a simple piecewise analysis procedure. A switching locus on the ω
