An article titled "Cursed circuits #5: capacitance multiplier" has been published on Substack, exploring the niche but enduring concept of capacitance multipliers in analog electronics. The piece has drawn attention on Hacker News, receiving 15 points though no comments as of this writing.
Capacitance multipliers are circuits that simulate a large capacitance using a smaller capacitor, often with active components like transistors. This technique is particularly useful in power supply filtering and audio applications where physical space is limited or large capacitors are impractical.
The article appears to be part of a series examining unconventional or "cursed" circuit designs. Such explorations appeal to hobbyists, engineers, and hardware enthusiasts interested in creative problem-solving within the constraints of analog electronics.
By revisiting older techniques, the piece highlights how fundamental circuit design principles remain relevant even in an age of digital dominance. It serves as a resource for those seeking to understand or apply analogue design tricks in modern projects.
Given the limited engagement, it remains unclear if this will spark broader discussion within the engineering community.
