Small signal model of common source amplifier
WebApr 17, 2024 · Sorted by: 1 This is correct small signal model of a common source MOSFET amplifier. You’ve placed Ro correctly across drain and source terminals. Also your input impedance would simply be R1 R2 while your output impedance is RD (1+ gmRs)Ro. This is a little more complex to derive but can be done with circuit analysis.

WebApr 10, 2024 · Small-Signal Models. After the BJT has been biased, we can focus on small-signal operation, and small-signal analysis is easier when we replace the BJT with simpler circuit elements that produce functionality equivalent to that of the transistor. Just remember that these models are relevant only to small-signal operation, and furthermore, … http://courses.ece.ubc.ca/elec401/notes/eece488_set3_1up.pdf
