Page 1 of 2 Homework 5 ECE 559 (Fall 2009), Purdue University ) c t r a P Decrease the threshold voltages of the NMOSs in the pull-down network. You can change the effective threshold voltages of the NMOSs by adding a battery at the inputs in addition to the input voltages applied so that gate-overdrive VGS - VT changes. You don’t need to change the threshold voltage in the library. Use battery voltage, VB = 0.8 V. Repeat Part b). You can consider breaking down the 16-inputs in multiple cascaded stages as necessary. Explain why or why not. Draw and submit your final schematic (on paper by hand is OK if you don’t use Cadence). Explain the differences in results with the Part b). Page 2 of 2...
