A) 4, 3.84
B) 3.69, 3.84
C) 4, 4
D) 4, 3.69
Correct Answer: A
Solution :
\[{{\operatorname{R}}_{o}}=800\Omega {{\operatorname{V}}_{o}}=0.8V\] \[\beta =0.96{{\operatorname{R}}_{1}}=192\Omega \] \[\Delta {{\operatorname{V}}_{o}}=\Delta {{\operatorname{I}}_{c}}\times {{R}_{o}}\] \[\Delta {{\operatorname{I}}_{c}}=\frac{0.8}{800}=1mA\] \[\operatorname{Voltage} gain {{A}_{v}}=\beta \frac{{{R}_{o}}}{{{R}_{1}}}=\frac{0.96\times 800}{192}=4\] \[\operatorname{Power} gain ={{\beta }^{2}}\frac{{{R}_{o}}}{{{R}_{1}}}=\frac{0.96\times 0.96\times 800}{192}=3.84\]You need to login to perform this action.
