comparator

What problem does it solve?

Simulates and analyzes StrongArm dynamic comparators with ngspice and Python to provide end-to-end insights into speed, noise, offset, and power for design sizing.

Core Features & Use Cases

• Transient waveform simulations to understand VX nodes, latch regeneration, and output timing.
• Noise extraction using probit methods and transfer-curve fitting to derive sigma_n and FOM values.
• Parameter sweeps for transistor widths and topology comparisons (StrongArm vs Miyahara) to study speed–power–noise trade-offs.
• Automated reporting including plots, logs, and FOM reports for engineering decisions.

Quick Start

Run python comparator/scripts/run_tran_strongarm_comp.py to execute the full StrongArm comparator suite.
