The slope of the I_D vs. V_GS curve of an n-channel MOSFET in linear region is 10^-3$${\Omega ^{ - 1}}$$ at V_DS = 0.1V. For the same device, neglecting channel length modulation, the slope of the $$\sqrt {{{\rm I}_D}} $$ vs. V _GS curve (in $$\sqrt A /V$$ ) under saturation region is approximately ______.

For the MOSFET M₁ shown in the figure, assume W/L =2, V_DD = 2.0 V, $$\mu n$$ C_OX = 100$$\mu {\rm A}/{V^2}$$ and V_TH =0.5 V. The transistor M₁ switches from saturation region to linear regionm when V_in(in Volts) is _____
