Normally-off junction field-effect transistors and application to complementary circuits
10038104 · 2018-07-31 · ·

A junction field-effect transistor (JFET) with a gate region that includes two separate sub-regions having material of different conductivity types and/or a Schottky junction that substantially suppresses gate current when the gate junction is forward-biased, as well as complementary circuits that incorporate such JFET devices.
