15.4 Let us consider the device conductance parameter

It is known that all four variables μ, C_ox, Wand L are random variables due to processvariations.

(a). Derive an expression for the percentage change in k due to percentage changesin μ, C_ox, W and L.

(b). If you assume that all four parameters change independently (corners technique),what would be the maximum percentage change expected due to 5% changes inall four parameters for nominal values of (μ^o, C_ox^o, W^o, L^o) = (980 cm²/V•sec,35x10⁻⁸ F/cm²,5 μm, 1.0 μm)?
