VLSI26: Open Source SAR ADC Modeling

[agurlask]

Summary

Uses open-source dynamical system simulation package PathSim to model a charge-redistribution SAR ADC.

The SAR ADC model includes common error sources including CDAC weight mismatch, kT/C sampling noise, comparator noise, and CDAC settling error.

Also, the notebook uses the SAR ADC model to simulate a published background calibration algorithm (offset double conversion - see Liu/Huang/Chiu Publication).

Instructions to Run Notebook

• Create a new python virtual environment in the same directory as requirements.txt
  • python -m venv .venv
• Activate the virtual environment
  • Run activate script (exact command is platform-dependent)
• Install the dependencies
  • pip install -r requirements.txt
• Open Jupyter Lab and run the notebook
