CMOS Hybrid Adder Architecture Analysis

This project centres on a high-speed hybrid full adder implemented in pure CMOS. The heart of the work is architectural: I need to see how different logic styles are blended inside the adder, why each stage is arranged the way it is, and how those choices influence delay paths while keeping power draw to an absolute minimum. Power efficiency is the primary optimisation target. Please quantify any architectural tweak in terms of dynamic and leakage savings, and be sure the final design still meets “full-speed” expectations under typical, slow, and fast corners. Deliverables • Complete transistor-level schematic or SPICE-compatible netlist of the selected hybrid architecture • Simulation decks, waveform outputs, and a concise comparison versus at least one conventional CMOS adder • A reproducible PDF report (~10 pages) that explains the architectural rationale, shows power-delay results, and highlights trade-offs State all assumptions clearly—process node, supply voltage, load, and device sizing—so I can rerun your setup in Cadence Virtuoso, LTspice, HSPICE, or a similar tool without guesswork.
