TWO NOVEL APPLICATIONS OF SPICE

Krishnapuram Kumar

Abstract


Two novel applications of SPICE in the area of (i) two circuit theorems’ parameter determination and (ii) voltage/current dependent sources’ delay time are given. In the first case, applications of SPICE in obtaining Thevenin/ Norton’s equivalent circuit voltage/current and immittances are demonstrated. A SPICE file which prints all the four Thevenin/Norton parameters simultaneously is described. In the second application, the time delays in the dependent sources ( which are used in simulating small signal equivalent circuits for high frequency devices (Bipolar, HEMT) used in time and frequency domains) are realized by suitable SPICE compatible techniques. Simulation results in the frequency domain incorporating these delays for two types of devices are plotted.
