Abstract
A switching circuit can have a plurality of first signal lines of a programmable logic device, a plurality of second signal lines of the programmable logic device, and a plurality of switch elements. Each switch element can selectively couple one first signal line to a second signal line and include one or more switch junction field effect transistors (JFETs) having a first control gate separated from a second control gate by a channel region.
