WebMay 22, 2024 · A common collector amplifier using two-supply emitter bias is shown in Figure 7.4. 1. The input is coupled into the base like the common emitter amplifier, however, the output signal is taken at the emitter instead of at the collector. Because the collector is at the AC common, there is no need for a collector resistor. WebEngineering Electrical Engineering (Example 4.13) Consider a common-emitter circuit using a BJT having Is = 10-15 A, Rc=6.8 k2, and Vcc= 10 V. a) Determine Ic and VBE required to have VCE=3.2 V. b) Find A, at this bias point.
