Low-Power 4-bit Comparator with Pre/Post-Layout Analysis

Full-custom CMOS comparator design with layout-level power and delay estimation

A low-power 4-bit magnitude comparator designed at the transistor level, with schematic simulation followed by physical layout, comparing pre-layout and post-layout power and delay figures.

What's included

  • Transistor-level schematic design of a 4-bit comparator
  • Low-power design technique applied and justified
  • Physical layout with DRC/LVS clean verification
  • Pre-layout vs. post-layout power and delay comparison
  • Full report with schematic, layout and waveform screenshots
