An $n$-channel depletion MOSFET has following two points on its $\mathrm{I}_\text{D}-\mathrm{V}_{\text {GS}}$ curve
- $\text{V}_{\text{Gs}}=0$ at $\text{I}_\text{D}=12 \mathrm{~mA}$ and
- $\mathrm{V}_{\mathrm{GS}}=-6$ Volts at $\mathrm{I}_{\mathrm{D}}=0$
Which of the following $\text{Q}$-points will give the highest trans-conductance gain for small signals?
- $\mathrm{V}_{\mathrm{GS}}=-6 \; \text{Volts}$
- $\mathrm{V}_{\mathrm{Gs}}=-3 \; \text{Volts}$
- $\text{V}_{\text {Gs }}=0 \; \text{Volts}$
- $\mathrm{V}_{\mathrm{Gs}}=3 \; \text{Volts}$
