engineering recuitment GATE ECE 2023-24 Test Series Analog Electronics Bipolar Junction Transistors BJT As a Amplifier
A cascade of two voltage amplifiers A1 & A2 is shown in the figure the open-loop gain \({A_{{v_0}}}\), input resistance Rin, and output resistance R0 for A1 and A2 are as follows:
A1: \({A_{{v_0}}}=10\), Rin = 10 kΩ, R0 = 1 kΩ
A2 : \({A_{{v_0}}}=5\), Rin = 5 kΩ, R0 = 200 Ω
The transfer function Vout/Vin is:
