Question

In the CE-RC coupled amplifier uses transistors with the following h-
parameters: hfe=50, hie=1100, hoe = 10u mhos, hre = 2.5 x 10-4
. The
value of gm at the operating point is 200 mmhos. The biasing resistor
R1 and R2 may be neglected being large in comparison with Ri. The
load resistor Rc=5kohm. Let the total shunt capacitance C=200 uF in
the input circuit and the coupling capacitor Cc=7uF. Calculate for one
stage of the amplifier (a) mid band current gain (b) mid band voltage
gain (c) lower and higher 3dB frequencies and (d) gain-bandwidth
product.
