What is the subthreshold leakage current in nanoamps for an NMOS FET at 300°K when it has Vgs = 171mV ? Assume that this MOSFET has a steep retrograde body doping profile with a maximum depletion region thickness of Wdmax = 38nm, and an effective oxide thickness, Toxe, of 33 angstroms. Use: W = 7.1μm, L = 0.3μm, Vt = 372mV and kT/q = 26mV at 300°K. Note that since the answer for this question may be very small, be sure to give your answer to at least 3 significant figures!
