FET matching and testing made simle
Many designers shy away from using JFET transistors although numerous circuits would benefit from using these devices. Whenever very high input impedance, high operating frequency and relatively low noise are paramount design requirements, a JFET may be a good choice. This article aims at removing some of the general hesitation about using JFETs by describing a simple tester that allows you to measure two crucial electrical parameters of these devices.
