Ball a, of mass ma, is connected to ball b, of mass mb, by a massless rod of length L. (Figure 1 )The two vertical dashed lines in the figure, one through each ball, represent two different axes of rotation, axes a and b. These axes are parallel to each other and perpendicular to the rod. The moment of inertia of the two-mass system about axis a is Ia, and the moment of inertia of the system about axis b is Ib. It is observed that the ratio of Ia to Ib is equal to 3: Ia Ib = 3 Assume that both balls are pointlike; that is, neither has any moment of inertia about its own center of mass.

An NMOS amplifier is shown in Figure 1. Transistor M1 is biased in the saturation region for an amplifier application. The circuit is biased with a resistive voltage divider consisting of R1 and R2, a source degeneration resistor RS, and a load resistor RD. The drain bias current for the design is ID = 500 μA and VDS is 1.625 V. The device parameters are: L = 0.5 μm, W = 10 μm, kn’ = 200 μA/V2, Vtn = 0.5 V, and λn = 0. analyze the frequency response of the amplifier. a) Draw a midband small signal ac equivalent circuit model for the amplifier. For midband you can assume the reactance of Cin is sufficiently low that it is a short circuit. b) Derive an expression for the midband voltage gain transfer function Vout /Vsig. The amplified output signal is taken from the drain terminal and Vout = Vd. Write your gain function in terms of variables only. c) Evaluate the midband gain and calculate a value both in V/V and dB. d) Analyze the frequency response of the input network including the capacitor Cin. Find an expression for the transfer function H1(jω) = Vg/Vsig. e) Evaluate H1(jω) = Vg/Vsig and make a Bode plot of the magnitude of H1(jω). The x-axis is ω (log scale) and the y-axis is the magnitude in dB. f) Use the LTSPICE circuit template and verify the frequency response of the amplifier circuit. Include a copy of the schematic and the frequency response plot. Use 20 points per decade and a frequency span of 0.1 Hz to 100 Hz.

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?
