Question

Figure P11.34 shows a common gate amplifier configuration using an $n$-channel depletionmode transistor. The $Q$-point for this circuit is chosen to be $I_D=5 \mathrm{~mA}, V_{D S}=5 \mathrm{~V}$, and $V_{G S}=-2 \mathrm{~V}$. (a) Calculate the values of resistances $R_S$ and $R_D$. (b) What is the slope of the dc load line? (c) What is the slope of the ac load line? Figure P11.34 can't copy

Instant Answer

Step 1

The voltage across \( R_S \) can be calculated using the formula: \[ V_S = I_D \cdot R_S \] Given that \( V_{GS} = V_G - V_S \) and \( V_G = 0 \) (assuming the gate is connected to ground), we have: \[ V_S = -V_{GS} = -(-2 \, \text{V}) = 2 \, \text{V} \] Now Show more…
