The CE amplifi er of Fig. P6.11 utilizes the feedback-bias scheme. Assume the BJT is biased at IC 5 1 mA, and has 0 5 150, VA 5 75 V, rb 5 300 V, fT 5 500 MHz, and C 5 0.3 pF. Estimate a0 and f23 dB...

The CE amplifi er of Fig. P6.11 utilizes the feedback-bias scheme. Assume the BJT is biased at IC 5 1 mA, and has 0 5 150, VA 5 75 V, rb 5 300 V, fT 5 500 MHz, and C 5 0.3 pF. Estimate a0 and f23 dB if Rsig 5 1.0 kV, RC 5 10 kV, and RB 5 100 kV. Hint: beware that both C and RB are subject to the Miller effect.
