Related Issues

The integrated circuits designed in this contribution are part of my work in the FOSSEE Summer fellowship 2025 in eSim

Purpose

To complete my internship work & to contribute my knowledge in the Open Source community

Approach

All Integrated Circuits are designed from scratch (using CMOS) using Sky130 PDK

Below Integrated Circuits are contributed by me:
