Question

In a common emitter amplifier, using output resistance of 5000 Ω and input resistance of 2000 Ω , if the peak value of input signal voltage is 10 mV and β = 50 is given. Find peak value of output voltage -, 5 × 10 - 6 V, 2 .5 × 10 - 4 V, 1 .25 V, 125 V

MARKS App · Accepted Answer

for CE amplifier Voltage gain A = β R o R i A = 50 × 5000 2000 ; A = 125 = v o u t p u t V i n p u t ; 125 = V 0 10 m V ; V 0 = 1.25 V
