An Implementation of a simplified version of the EKV MOSFET Model in Matlab and Verilog-A for simulation in Cadence

摘要

The paper presents an open source implementation of the EKV MOSFET compact model in Matlab and in Verilog-A codes; the Verilog-A code is simulated in Cadence Spectre circuit simulator. The implemented EKV model uses a simplified formulation given by Godfrey and Lazzaro with explicit threshold voltage (rather than explicit pinch-off voltage). Verification is performed against measurements taken from the literature and against the simulation results obtained by simulation with the conventional BSIM3v3 compact model of a 0.35 μmCMOS technology design kit.
