WebDec 10, 2024 · In the T-equivalent circuit model of a MOSFET in small signal analysis the MOSFET shows an infinite resistance between its gate and source when looking from the gate while it shows very little resistance when looking from the source. I can't see how it can shows two different resistances like that. If the current has no path from the gate to ... WebSmall-Signal Response of MOSFET Circuits Consider this circuit, which has both a DCand an AC small- signalsource. As a result, each voltage and current in the circuit has botha DC and small-signal component. gs If the MOSFET is in saturation, then the totaldrain current is: 2 2 22 2 D GSt GS gs t GS GSttgsgs fitch ratings on adani
