ECE3060: VLSI and Advanced Digital Design Fall 2007 Homework #1: Solutions 1. Draw the transistor-level schematic of the following binary functions using the minimum number of transistors. Assume that the inputs are available in both true and complemented forms. (a) F = ¯ a ( ¯ b + c ) + a Minimized F = ¯ ab ¯ c (b) F = b ( ac + ¯ e ) + ¯ b ( a + ¯ cd ) + ab Minimized F = ¯ a ( ¯ b + e )( b + c + ¯ d )
