This paper presents an approach to automate MOS-Only circuit design under the polynomial regression and surface fitting. The proposed scheme incorporates a unified model, which enables to improve simulation accuracy in standard SPICE and Cadence SPECTRE simulators during the MOS-Only designs. Furthermore, a piecewise polynomial regressive model of transconductance (g(m)) of the MOS transistors is presented in terms of V-DS, channel width (W) and channel length (L) to increase automation efficiency. Exemplary results are given at high frequency operation to validate our model in both Cadence Spectre and LT-Spice as well.
