For following circuit, both MOSFET transistors have following parameters: Vth = 0.5 V and μn Cox = 0.4 mA/V^2. L1 = L2 = 0.18 μm and W1 = 0.72 μm, W2 = 1.8 μm. The VD1 is measured to be 0.7 V. If the transistor Q2 is operating at the edge of saturation region, determine ID1, R, ID2, VD2, and R2. VDD = 1.8 V
