Multistage amplifier: Cascade of two CE stages
Aim:
To construct a high gain amplifier by cascading two gain stages: (i) calculate gain and (ii)
study the frequency response of the amplifier
Procedure:
1. Construct the circuit shown in Fig.3. Measure and record the mid-band AC voltage gain
with a sinusoidal signal.
2. Study the frequency response of this circuit to draw frequency vs gain curve. Determine
the lower and higher frequency cut off
