10.4 The Feedback Voltage Amplifier (Series–Shunt)
The College of New Jersey (TCNJ) – ELC251 Electronics Ihttp://anthony.deese.googlepages.com
Based on Textbook: Microelectronic Circuits by Adel S. Sedra (0195323033)
10.4 Summary
▪ 1. Ri and Ro are the input and output resistances, respectively, of the A circuit in Figure 10.15(a).
▪ 2. Rif and Rof are the input and output resistances, respectively, of the feedback amplifier, including Rs and RL (see Figure 10.14a).
▪ 3. The actual input and output resistances of the feedback amplifier exclude Rs and RL. These are denoted Rin and Rout in Figure 10.14(a) and can be determined via equations (10.25) and (10.25).
Example 10.4It is required to analyze this amplifier to obtain its voltage gain Af , input resistance Rin , and output resistance Rout
