F Frida New Member Dec 11, 2011 #1 This is from a FET-transistor. https://i.imgur.com/wRvB9.jpg **broken link removed** I would like to express Uut(t) with Ugs! I would write it as: Uut(t)= gmUgs*(RL//Rs) but then the voltage amplification is not reasonable. Thanks for the help! /Frida Last edited: Dec 11, 2011

panic mode Well-Known Member Dec 18, 2011 #2 what is on left side of the circuit (shows open)? it looks like you are trying to solve small signal model for MOSFET. show original circuit before reducing it to a small signal model. Last edited: Dec 18, 2011
