Calculate gm for a JFET with IDSS = 8 ext mA, VP = -3 ext V, operating at VGS = -1 ext V.

Here are the solutions to the problems:

: Calculate $g_m$ for a JFET with $I_{DSS} = 8 \text{ mA}$, $V_P = -3 \text{ V}$, operating at $V_{GS} = -1 \text{ V}$.

Step 1: Calculate the transconductance at $V_{GS} = 0$, $g_{m0}$.

$$g_{m0} = \frac{2 I_{DSS}}{|V_P|}$$ $$$$
