Question

4. Consider the following JFET based amplifier: R1 600 Ohm Vbatt 10k Ohm Input R2 vin(t) (a). Derive an expression for the total voltage, Vout (relative to ground) if the transconductance gm of the JFET is 0.008 Mhos, treating Vin(t) as an unknown. (10 points) (b). Identify the AC gain of the amplifier - this is the coefficient of Vin(t) in your answer from part (a). Express the gain in dB units (e.g. 20 logiolVout/Vinl) (5 Points) (c). Is this an inverting or non-inverting amplifier? (5 points)
