Q2. Consider the CMOS amplifier shown below. The circuit has the following parameters: VDD = 2V, Vth = 0.3V, kn = 2mA/V2 and RF=RD=1kΩ. The input voltage source has zero source impedance.  Calculate the value of Vin for which the transistor moves from saturation to linear region. For linear region, use the following I-V equation
