1. The problem statement, all variables and given/known data A bypass capacitor increases gain in the mid-band region. Explain how with the figure and small signal model. Assume gm=0.5mS. 2. Relevant equations Rs = 1 k Ohm 3. The attempt at a solution With the bypass capacitor, the source would be treated as grounded and the eqautions to find gain would be: Vo= -gm x Vgs x Rd Vgs= Vsig x R1||R2 / (R1||R2 + Rsig) How does the source resistor effect the circuit? Vgs will be different because Vs will no longer be 0. Vs will be gm x Vgs x Rs. Thank you.
