Chapter 7, Problem 7.5TYU

The common−emitter circuit shown in Figure 7.34 contains both a coupling capacitor and an emitter bypass capacitor. (a) From a computer analysis, determine the 3dB frequency. Assume the parameter values are $\beta =100$ and $I_S=2\times {10}^{\text{-15}}\text{A}$ . (b) Determine the midband small−signal voltage gain. (Ans. (a) $f_{3dB}\approx 575\text{Hz}$ , (b) ${\left|A_{\upsilon }\right|}_{\max }=74.4$ )
