Inside a 1980s switched-capacitor filter chip
Original: A 1980s filter chip that uses switched capacitors
A detailed teardown published on the Righto blog examines a 1980s-era filter chip that uses switched-capacitor circuitry, explaining how the device performed signal filtering on a single silicon die. The article walks through the chip's design and why switched-capacitor filters were a notable advance, letting circuits replace bulky external resistors and capacitors. Readers are discussing the retro engineering and the elegance of the approach.
Why now: Detailed reverse-engineering write-ups of vintage chips consistently draw interest from engineers nostalgic for 1980s technology
