The initial parameters of an n-channel MOSFET are Cox μn = 0.15 mA/V2, L = 1.2 μm, W = 6.0 μm, and VT = 0.45 V. The device operates over a voltage range of 0 to 3 V (i. e. , 0 V < VG < 3 V ). Consider a case where the device needs to be scaled down to lower dimension. As the dimension of the MOSFET is scaled down, parameter VD, L, and μ are scaled by k and Coxμn is scaled by 1/k. Assume the scaling factor of k = 0.65, but the threshold voltage is held constant. (a) Determine the maximum drain current in the (i) original device and (ii) scaled device. (b) Determine the maximum power dissipation in the (i) original device and (ii) scaled device. Note the power dissipation can be calculated by multiplying drain voltage VD by maximum drain current ID(max) (i. e. , P(max) = ID(max)×VD)

ID = WμnCox 2L[2(VGS − VT)VDS − VDS2] (0 ≤ VDS ≤ VDS(sat)) (a) Derive the saturation drain voltage (VDS(sat)) as a function of (VGS − VT). (b) Derive the saturation drain current (ID(sat)) as a function of (VGS − VT). (c) For very small VDS, describe how to experimentally determine both parameters, i. e. , (i) electron mobility (μn) and (ii) threshold voltage (VT). (d) Derive the transconductance (gm) at the saturation point as a function of VDS. (e) Assume that this n-channel MOSFET has the following parameters: channel length (L) = 1.25×10−4 cm, electron mobility (μn) = 650 cm2 /V−s, gate oxide (SiO2) capacitance (Cox) = 6.9×10−8 F/cm2, and threshold voltage (VT) = 0.65 V. Determine the channel width (W) such that ID (sat) is 4×10−3 A when VGS = 5 V.

Question 1. Current calculations in 180 nm node MOSFET transistor technology I An n-MOSFET is fabricated in 0.18 μm technology characterized by the following process and device parameters: VDD = 1.8 V, Vtn = 0.5 V, L = 0.18 μm, Wn = 0.27 μm and a SiO2 thickness of 4 nm, in the usual notation. Take the relative dielectric constant of SiO2 to be 3.9 and ε0 to be 8.85 ×10−12 F/m. (a) What is the process transconductance parameter, kn, if the electron mobility is 400 cm2 /Vs. Express your answer in A/V2 and μA/V2. Explain why the units of kn are A/V2 or μA/V2. (b) If the mobility of holes in silicon is 1 /3 that of electrons, by what factor will kp differ from kn ? Why is this important? (c) What is the capacitance per unit area (Cox) for a 10 nm thick SiO2 ? The SI unit of areal capacitance is F/m2 but device engineers often use F/cm2 or fF/μm2. Express your answer in both these units as well. Instead of calculating the capacitance per unit area again for different oxide thicknesses device engineers may employ a scaling argument. How would your answer above change if the oxide thickness was (i) increased to 20 nm, (ii) reduced to 3 nm or (iii) reduced to 1 nm (d) How much drain current flows in the transistor if VDS = 0.2 V and VGS = 0.8 V ? Express your answer in μA per micron of device width. Why do you think it is useful to express the drain current as the drain current per μm device width?
