This course will be an in-depth introduction to Bandgap Reference (BGR) design and layout using open-source EDA tools (ngspice & Magic) and Google’s Skywater 130nm (SKY130) open-source process design kit (PDK). The course will focus on intuitive understating of the concepts involved in designing a BGR with real-world specifications and complete hands-on practice using the open-source EDA tools. During the 100 min course, the participant will start with the basic principles of BGR circuit, design, simulate and layout a complete industry-grade BGR – all of that in just 100 mins!

Day 1 – BGR Theory and Lab setup

• Why temperature-independent voltage/current references for ICs
