What will be the Gm, Rout & Av= Gm * Rout of a single-stage Common Drain amplifier
Hi All,
What will be the expression of Gm, Rout & Av= Gm * Rout of a single-stage Common Drain amplifier.
Here Gm is trans-conductance of the amplifier.
If over all gain Av = (gm * Rs ) /(1+gm*Rs) & Rout = Rs || (1/gm) = Rs /(1+gm*Rs) then
Gm =gm .
But Gm = f(Vin) while gm =f(Vgs).
Please correct me.
