In common emitter amplifier, the current gain is 62. The collector resistance and input resistance are 5kΩ and 500Ω respectively. If the input voltage is 0.01 V, the output voltage is: |
0.62 V 6.2 V 62 V 0.01 V |
6.2 V |
$\frac{V_o}{V_i}=β=\frac{R_o}{R_i}=\frac{62×5×10^3}{500}=620$ $∴ V_o = 620V_i = 620×0.01 = 620$ |
