How to choose JFET operating mode ?
Hi guys,
I'm trying to figure out how to choose optimal JFET operating mode. JFET (2SK170) will be used as a lower element of cascode circuit with tube sitting above it. What I'm looking for is what the operating mode/point which would make JFET operate in more linear fashion. Or whether lower/higher voltage/current would make it more quiet. Is it lower / higher drain / source voltage? Is it lower / higher current ? Are there any guidelines there ? Any input will be very appreciated. Thanks Sergey |
