Question

Difference between large signal and small signal model of mosfet

Answer 1

a small signal model take a circuit and based on an operating point and linearized all the component. nothing changed because the assumptions is that the signal is so small that the operating point doesn't change
BUT
LARGE SIGNAL MODELLING IS COMMON ANALYSIS METHOD used in electronics engineering TO DESCRIBE NON-LINEAR DEVICE IN THE TERM OF underlying nonlinear equation. THAT'S ALL
