Chapter 7, Problem 7.2EP

The circuit shown in Figure 7.10 has parameters of $R_P=7.5\text{kΩ}$ and $C_P=80\text{pF}$ . The midband gain is −2 dB and the lower corner frequency is $f_L=200\text{Hz}$ (a) Determine $R_S$ , $C_S$ , and the upper corner frequency $f_H$ . (b) Determine the open−circuit and short−circuit time constants. (Ans. (a) $R_S=1.94\text{kΩ}$ , $C_S=0.0843\mu \text{F}$ , $f_H=1.29\text{MHz}$ ; (b) ${\tau }_S=0.796\text{ms}$ , ${\tau }_P=0.123\mu \text{s}$ )
