You have to fabricate a CMOS inverter in the latest 3-nm technology (L = 3 nm), for which VDD = 1.3 V, Vtn = |Vtp| = 0.4 V, (W/L)n = 5, and kn′ = 4.2kp′ = 450 mA/V2. a) Find the Noise Margins and total area for the following conditions: i. Match case (kn = kp) ii. Wp = 2.1Wn b) Which condition would you choose between the two previous and explain why? c) Find the dynamic power if you know that the total equivalent capacitance at the output will be C = 15 fF and you are required to operate the inverter at f = 2.6 GHz. d) For the case when (W/L)p = 2.1(W/L)n, find the propagation times ( tPHL, tPLH and tp). Assume again C = 15 fF.

For the amplifier below, following design information is provided: VDD = 3.3 V, R = 2.4 kΩ, ISS = 1.8 mA, k1 = k2 = 5 mA/V2, VTH,1 = VTH,2 = 0.5 V, λ = 0.1 V−1, γ = 0, ki′ = μ0Cox, ki = μ0 Cox(W L)i. Assume that both transistors are identical and in the saturation region. Finally, NMOS and PMOS bulk terminals are connected to the ground and VDD, respectively. a) What is the DC bias voltage for M1 and M2 given that the voltage drop across ISS is 0.4 V ? You can neglect the channel length modulation, here. Check that the transistors are in the correct operation-mode. b) The resistors will be realized using identical PMOS transistors M3 and M4. If the transistors to be used will have k3 = k4 = 1.5 mA/V2, what will be their overdrive voltages? Check that the transistors are in the correct operation-mode. c) What is the differential voltage gain AV,diff = Vout/Vid in dB ? d) ISS will be realized as a cascode current source. Assume that the voltage drop of 0.4 V is equally shared by the two transistors, M5 and M6 having k5′ = k6′ = 0.5 mA/V2 and VTH, 5 = VTH, 6 = 0.5 V. Assuming the gate voltages of both transistors are 1 V, find the W/L ratios of each device. Once again, you can neglect the channel length modulation here. e) Considering (d), how would the W/L ratios qualitatively change (increase/decrease/stays the same), if γ > 0 ? Explain your reasoning analytically, i. e. , using appropriate equations. f) Using the cascode current source, calculate the common-mode gain of the circuit AV, CM = Vout /Vin in dB, where Vin . s applied to the gates of both M1 and M2. Assume λ = 0.1 V−1 for M5 and M6. g) Calculate the CMRR of the circuit in dB.

In the following CMOS inverter logic gate, assume the transistor size of (W/L)n = 0.8 μm/0.20 μm and (W/L)p = 1.6 μm/0.20 μm and VDD = 3.0 V. (a). Determine the operation modes (e. g. cut-off, linear or saturation) of the NMOS and PMOS transistors respectively at Vin = 0.2 V, 0.9 V, 1.5 V, 2.1 V, and 2.8 V. Using a table to list the operation modes is recommended. (Note: You may need to do multiple calculations for the data point Vin = 1.5 V with Vin = 1.4 V or 1.6 V). (b). Using the tabulated results in (a) or otherwise, determine the current flowing through both the NMOS and PMOS transistors at the different input voltage Vin in (a). (c). Using Matlab or Excel, plot a graph of the current against the input voltage Vin. (d). Using the above results in (a) and (b) or otherwise, determine the output voltage Vout at the different input voltage Vin in (a). (e). Using Matlab or Excel, plot a graph of the voltage transfer characteristics (VTC) (i. e. output voltage Vout versus input voltage Vin ) of the CMOS inverter with the five sets of data points obtained. It is given that the threshold voltage VTon = 0.50 V and μnCox = 430 μA/V2 for the NMOS transistor while VTop = −0.50 V and μpCox = 210 μA/V2 for the PMOS transistor. Assume the long-channel approximation of the MOSFET and there is no body effect (i. e. the body terminal of the MOSFETs are properly connected respectively to ground and VDD).
