A ramping method combined with the damped PTA algorithm to find the DC operating points for nonlinear circuits

The pseudo transient-analysis method is regarded as one of the most effective method to find DC operating points for nonlinear circuits. In this paper, we combine the ramping method and the damped pseudo-transient analysis algorithm together in order to improve the simulation efficiency. By combing the two algorithms together, the oscillation problem and time-consuming problems can be greatly eliminated. Numerical examples are shown to demonstrate the efficiency of proposed algorithms.
