Question

For a CE-transistor amplifier the audio signal voltage across the collector resistance of 2 kohm is 2 V Suppose the current amplification factor of the transistor is 100, find file input signal voltage and base current if the base resistance is 1 kohm.

Answer 1

Given,

Output voltage, V_o = 2 V

Output resistance, R_o = \(2k \Omega\)

Base resistance, R_i = 1k\(\Omega\)

Current amplification factor, \(\beta = 100\)

Then input signal voltage is,
