Cursed Circuits #5 Examines the Capacitance Multiplier

Cursed Circuits releases its fifth episode focusing on the capacitance multiplier. The article is hosted on the lcamtuf Substack page. It explains the circuit’s principle of boosting effective capacitance using active components. The author highlights common pitfalls that make the design feel “cursed.” Schematics and calculations are provided for readers to follow. Practical tips for building and testing the circuit are included. Understanding the multiplier helps designers achieve larger time constants with fewer parts. The piece invites hobbyists to experiment and share their results.
