railway RRB JE (CBT I + CBT II) Mock Test 2024 Analog Electronics Field Effect Transistors Types of FET
The transconductance gm of a JFET is equal to:
1
\(\frac{-2 I_{D S S}}{V_{P}}\)
2
\(\frac{2}{\left|V_{P}\right|}\left(\sqrt{ I _{ DSS }- I _{ D }}\right)\)
3
\(\frac{-2 I _{ DSS }}{ V _{ P }}\left(1-\frac{ V _{ GS }}{ V _{ P }}\right)\)
4
\(\frac{I_{D S S}}{V_{P}}\left(1-\frac{V_{G S}}{V_{P}}\right)\)
