Question
Calculate the value of $g_{m}$ for a JFET $\left(I_{D S S}=12 \mathrm{~mA}, V_{P}=-3 \mathrm{~V}\right)$ at a bias point of $V_{G S}=$ $-0.5 \mathrm{~V}$
Step 1
First, we need to find the drain current (ID) at the given bias point (VGS = -0.5V). We can use the following equation for JFET: $$I_D = I_{DSS} \left(1 - \frac{V_{GS}}{V_P}\right)^2$$ Show more…
