The sinusoidal collector-to-emitter voltage varies above and below its Q-point value, V CEQ, 1808 out of phase with the base voltage, as illustrated in Figure 6–2. A transistor always produces a phase inversion between the base voltage and the collector voltage. A Graphical Picture The operation just described can be illustrated graphically ...
