In this Design Idea, we explore several ways to use SPICE [1-3] circuit analysis software to determine the Thevenin and Norton equivalent circuit parameters of linear active networks. The Thevenin ...

A variety of linear models are available to represent common active electronic devices such as transistors and vacuum tubes. Devices operating under large-signal conditions often require nonlinear ...

This course teaches how to design a feedback system to control a switching converter. The equivalent circuit models derived in the previous courses are extended to model small-signal ac variations.

Download this article in PDF format. If you search the internet for “transformer equivalent circuits,” you’ll get five pages of over 100 small circuit diagrams. Figures 1 and 2 show two typical ...

What is hard about analyzing feedback circuits is the extraction from the circuit diagram of the simple block diagram found in active circuits and control textbooks. To start with a relatively easy ...
