In this question assume any transistors are fabricated in 180 mm node technology. (a) You are asked to design the realisation of the following CMOS logic operation Y = A + B ⋅ (C + D + E) subject to the following performance criteria that the transistor dimensions in the pull-up (pull-down) network should be able to provide a current of at least that found in a PMOS (NMOS) transistor with a (W/L) ratio equal to p(n), respectively. (i) Sketch the arrangement of transistors using static CMOS logic which would realise Y. (ii) What is the width of each transistor in the network? Show clearly your calculations.

Design a complex CMOS gate implementation of the following function: Y = A⋅(B + C)⋅D¯ a) Draw a logic circuit schematic for Y in which the Pull-Up Network (PUN) is the dual of the Pull-Down Network (PDN). Make sure to draw any necessary inverters for inputs. b) Assume that a basic matched inverter has a channel length of L = 0.25 μm, an NMOS channel width of WN = 0.5 μm and a PMOS channel width of WP = 1.0 μm, and that this sizing guarantees at least equal output current driving capability (i.e., equal high-to-low and low-to-high propagation delays). Determine the proper W/L ratios for each transistor in the complex logic gate to ensure a current driving capability at least equal to that of the basic matched inverter. Keep the W/L ratios as small as possible to minimize the gate's area. Calculate the total area of the complex CMOS circuit, including the area of the inverters for inputs.
