Hello Guys,
I started designing the common emitter amplifier with below specification.
Design Specification :
VCC = 12V
IC = 4mA
AVOL = 70
I have done some calculation to find all values needed in below circuit. When i run the simulation i found the gain of amplifier is 4.
I have expected the output voltage is 50mV*70 = 3.5Vpeak.
Could anyone figure the reason why the gain is only 4 ?
How do i can find close loop gain ?
Many thanks
