In the amplifier circuit shown in Figure 3 the input resistance R= 100 0, R. = 20 Q, the blocking capacitor C. has a value of 100 nF and A, = 100 (independent of frequency). Given that the output voltage v. = 500 mV at mid-band frequencies for an input signal voltage (v.) of 15 mV, use the information in the question to find the values of R, and R, and the upper and lower cut-off frequencies (f, f) for this circuit. The load resistance R. is chosen to provide maximum power transfer to the load at mid-band frequencies and the stray capacitance at the output, C = 7.96 nF. voltage amplilying device (VAD) R, R R, Figure 3
