A look inside a 1980s switched-capacitor filter chip

Original: A 1980s filter chip that uses switched capacitors

A detailed teardown examines a 1980s filter chip that used switched capacitors instead of conventional resistors to perform analog signal filtering. The article explains how the chip switches capacitors at high speed to emulate resistance, a technique that made such filters easier to manufacture on a single die. Enthusiasts of retro silicon and analog circuit design are discussing the engineering trade-offs and the chip's place in electronics history.

Why now: Hardware history and chip teardowns reliably draw strong interest from engineers and hobbyists online.
