Abstract :
We consider the numerical solution of a system of ordinary differential equations, partial differential equations and algebraic equations arising from simulation of radio frequency circuits in which the transistors are described by partial differential equations. An iterative algorithm is presented together with new techniques to find a good initial guess of the solution. The algorithm is applied to the simulation of a voltage-controlled oscillator and the results are compared with those obtained by MEDICI.
