Abstract

We present an iterative algorithm to compute the response of an RF circuit in which the MOSFET is modeled by a system of partial differential-algebraic equations, rather than an equivalent circuit. The problem amounts to the solution of a nonlinear PDE coupled to a linear ODE. We illustrate the algorithm with the simulation of the Colpitts oscillator
