20 ree linear amplifier circuits are co ree linear amplifier circuits are c ad are connected as shown below. 20k R: R, R, A 20 etermine the following a) Net Loaded Voltage Gair b) For v, 20 mV. determi

Solution

Net loaded voltage gain=A1*A2*A3=20*10*4=800
Voltage gain=Vo/Vs=800
Output voltage=800*20*10^-3=16Volts
