An Analytical Gate-All-Around MOSFET Model for Circuit Simulation

Abstract EN

A generic charge-based compact model for undoped (lightly doped) quadruple-gate (QG) and cylindrical-gate MOSFETs using Verilog-A is developed.

This model is based on the exact solution of Poisson’s equation with scale length.

The fundamental DC and charging currents of QG MOSFETs are physically and analytically calculated.

In addition, as the Verilog-A modeling is portable for different circuit simulators, the modeling scheme provides a useful tool for circuit designers.
