Answer:
The open circuit voltage gain is [tex]A_{vo}=-10^{3}[/tex]
Explanation:
Given data is input resistance of an amplifier is [tex]R_{in}=100k[/tex]Ω and output resistance of an amplifier is [tex]R_{o} =100k[/tex]Ω.
Trans conductance of an amplifier is [tex]g_{m}=10mA/V[/tex]
Thus Open circuit voltage gain is
[tex]A_{vo} =-g_{m}R_{o}[/tex]
[tex]A_{vo}=-10[/tex]×[tex]10^{-3}[/tex]×100×[tex]10^{3}[/tex]
Since 1m=[tex]10^{-3}[/tex] and 1k=[tex]10^{3}[/tex]
Thus,
[tex]A_{vo}=-1000[/tex]
[tex]A_{vo}=-10^{3}[/tex]
