The circuit presented by Cor Van Rij for characterizing JFETs is a clever solution. Noteworthy is the use of a five-pin test socket wired to accommodate all of the possible JFET pinout arrangements.

Commercial curve tracers have existed for decades. But designers without access to one can create a simple circuit that uses a function generator and oscilloscope to generate JFET transfer and ...

Editor’s note: This article is based upon a 2006 EDN article by Jim Williams; see Reference 1. There are six different types of FETs, but of the two major categories of FETs, enhancement mode devices ...

As fundamental components of many devices and electronic instruments, field effect transistors (FETs) are important semiconductor devices. A FET is a majority charge-carrier device in which the ...
