Clear reasoning.
Traceable decisions.

Analog IC Notes is an independent engineering notebook about the craft of transistor-level design.

The goal is simple: record the reasoning that usually disappears between a textbook equation and a finished simulation. Each note starts from assumptions, builds a compact model, and checks where that model stops being useful.

What belongs here

• Device-level intuition grounded in equations
• Design procedures that can be repeated
• Simulation plans, corner analysis, and postmortems
• Open questions worth carrying into the next design

Good analog design is not a bag of tricks. It is a disciplined conversation between models and reality.
