Common-Emitter (CE) Configuration

In the common-emitter configuration, the EMITTER terminal is common to both the input and output loops. The base current $I_B$ is now the input current (the input signal is applied between base and emitter), and the collector current $I_C$ is the output current (t …

Figure 9.27NPN transistor in common emitter configuration: schematic and circuit symbol

What this figure shows. Panel (a) draws the schematic circuit: an NPN transistor with bias source $V_{BE}$ connected between base and the (common) emitter, driving input current $I_B$ , and bias source $V_{CE}$ connected between collector and the same common emitter, with output current $I_C$ and the emitter current $I_E$ also marked. Panel (b) redraws the identical circuit with …
