Enhancement mode JFET

[syn08]

Replace JFET with "silicon JFET" and I would agree, at least for standard processes. For wide band gap semiconductors, discrete power JFETs with Vp>0 are commercially available.

These devices are allowing a much wider positive Vgs range, and the transconductance is much improved by the high carrier mobility in such semiconductors (like SiC), so no huge device area is required.

Sorry physics says so.

Ordering a white Merlot at the table, you'll get no Merlot whatsoever, but it will be white instead.

My oversite, getting old and never had cause to consider these.

There is no such thing as an enhancement mode JFET. There is no way to create a built in field to adjust the threshold like a MOSFET.

EDIT - It must be happy hour.

EDIT - hook, line, and sinker.
