The Art Of Analog Layout By Alan Hastings Jun 2026

Hastings doesn't just tell you to use "common-centroid" layouts. He explains why a gradient in oxide thickness across a wafer destroys matching. He shows you the visual patterns (interdigitated vs. common centroid) and explains the psychological trap: "A layout that looks symmetric often isn't electrically symmetric."

The single most cited chapter in Hastings’ book is the one on . In the digital world, a transistor is either "on" or "off." In the analog world, a transistor is a finely tuned resistor. If two transistors are supposed to be identical but aren't, your circuit fails. the art of analog layout by alan hastings

“We use the 'Hastings Matching Test' in our technical interviews. If a candidate can explain the difference between a dummy diffused resistor and a salicided polysilicon resistor using Hastings' examples, they are hired on the spot.” — Hastings doesn't just tell you to use "common-centroid"
