A comparison of two latency insertion methods in dependent sources applications

摘要

This paper compares two different formulations of the latency insertion method (LIM) for the analysis of circuits with dependent sources. One is the scalar LIM and the other is the amplification matrix LIM. Numerical experiments demonstrate that the scalar LIM necessitates much smaller time step than the amplification matrix LIM when handling certain types of dependent sources indicating better performance of the latter technique without a sacrifice in accuracy.
