The junction field-effect transistor, or JFET, although over 40 years old, is still solving real-world, small-signal-chain problems typically requiring low power, high impedance, and low noise. They also offer excellent radiation and temperature tolerance, required in many military/high-reliability applications.
This article will look at various topologies and applications which take advantage of the key features of JFETs such as low noise, low voltage, low leakage current, and high impedance. To read the article as a pdf file (no registration required), click here.
