The Art of Analog Layout by Alan Hastings is widely considered the "bible" of IC layout design. Since its publication, it has served as the definitive guide for engineers, designers, and students navigating the intricate world of integrated circuit design [1].
If you are serious about analog design, this book is an indispensable part of your library.
Before a design can be sent to the foundry (Tape-Out), it must pass rigorous automated software checks. the art of analog layout by alan hastings portable
The portable rule is “Don’t let the quiet see the noisy.” A p+ guard ring tied to ground collects injected minority carriers; an n-well ring tied to VDD creates a reverse-biased junction that absorbs noise. But beyond rings, Hastings stresses floorplanning: place analog blocks far from digital clocks, use separate power and ground pads (or deep n-well isolation in CMOS), and never run digital signals over analog circuitry. The substrate is not a neutral insulator—it is a conductor of chaos.
A circuit must survive the real world. The portable reference outlines the geometric layout rules required to prevent latch-up conditions and ensure robust Electrostatic Discharge (ESD) protection paths. Target Audience The Art of Analog Layout by Alan Hastings

Layout engineers often work with multiple widescreen monitors to view complex EDA (Electronic Design Automation) tools. Large textbooks take up valuable physical desk space. Before a design can be sent to the
Techniques for using guard rings, deep N-wells, and strategic routing to shield sensitive analog nodes from digital switching noise and substrate crosstalk.
One of the most critical aspects of analog design is ensuring that components intended to be identical actually act identically.
Analog layout is fundamentally different from digital layout. While digital design relies heavily on automated place-and-route software, analog design remains an art form. It requires deep human intuition and an understanding of solid-state physics. Small physical variations can ruin the performance of an analog circuit, making precision paramount.
