Consider the following structure of logic circuits. 2 Assume that the minimum sizing of NMOS is 2 unit (n = 2) and PMOS is 3 units (p = 3) with channel length 0.15 μm (L = 0.15 μm). Determine the width of each transistor, Q A , Q B , Q C , Qe , and Qp . (20%) 5. Consider the following logic diagram of AND-OR-INVERT gates, IC model SN74LS51, from Texas Instrument. Answer the following questions: a. Write the logic (Boolean) equation of the circuit above. (5%) b. Use complementary CMOS design to draw the circuit. Show pull-down network, pull-up network, VDD, and GND. (15%)...
