Consider the above MOSFET amplifier circuit and assume that the capacitors are infinitely large. MOSFET parameters are given to be: Vt = 0.9 V, and kn = 76 μA/V2. Component values are given as Rsig = 1.2 KΩ, R2 = 6 KΩ, RD = 3.4 KΩ, RS = 600 Ω and RL = 5.1 KΩ. Design the value for resistor R1 for setting an operating voltage of VDS = 12 V (express the result in KΩ units).
