The LDO needs to be designed for VDD = 1.8 V with load current I varying from 200μA to 2 mA. Ignore all the intrinsic capacitances of the pass transistor MP. Assume that the channel length modulation factor, Ap= 1 V-1, Hp Cox = 50 μA/V² and VTH = 500 mV. The value of compensation capacitor Cc is 200pF. Adhere to the units mentioned in the question while filling in numerical answers. VDD = 1.8V 9m1 = 300μ A/V D Emi VREF=0.7V 0 Vo1 Cc: R01 1Meg VFB Mp R₁200k R₂ W=? L=180nm 200ΚΩ Vo HHI COUT I₁ = 200μA to 2mA R₁ Figure 1 Fill in the blank with a numerical answer: The minimum channel width W (in respect of the circuit shown in Figure 1) that is required to keep Mp in saturation for the entire load range of 200µA to 2 mA is um (up to 1 decimal place).
