# Mos2P

Level 2 Grove-Frohman Mosfet Model (NMOS)

## Library

Analog/Basic

## Description

This is a MOS Level 2 (Grove-Frohman Mosfet Model)

The equations of the MOS level 2 give the evaluation of the current IDS between the drain and the source as a function of VD, VG and VS.

The device operation is divided into three regions:

- cut-off (Vgs <= Vth)

- linear (0 <= Vds <= Vgs-Vth)

- saturated (0 <= Vgs-Vth <= Vds)

The second order effect is taken into account (channel length modulation)

Equations for the MOS2N device

- when Vgs <= Vth then Ids=0

- when 0 <= Vds <= Vgs-Vth then the equations below apply:
