Hello,

I'm stuck on a textbook question.

If Igss (gate leakage current) is given as 50pA, and Id (drain current) is 1mA, then how to I find the EXACT Vgs in a Drain-Feedback E-MOSFET circuit?

I know that usually in this type of circuit that Vgs = Vds = Vdd - IdxRd

Vdd = 15v
Rg = 22 Mohms
Rd = 8.2 kohms

no Rs

if anyone can help, please email me at pmcallister@digitalme.com

thanks.
