Abstract

A MATLAB program for Volterra distortion analysis of ultra high speed weakly nonlinear circuit is presented. A Volterra series method and a nodal formulation are used in this program. Approximate expressions for the transfer function, the harmonic equations and third-order intermodulation distortion equation are given respectively. Simulations based on a commercially available 65 nm CMOS process technology are performed with both the Matlab program and the SpectreRF circuit simulator. It is shown that results obtained by the MATLAB program have a consistent match with those derived from SpectreRF simulator, whereas the overall computational efficiency has been improved.
