What are switched capacitor filters, amplifiers and integrators?

February 3, 2021 By Jeff Shepard Leave a Comment

Switched capacitors (SCs) are highly-versatile circuit elements that can be used to provide various functions, ranging from micro-scale implementations embedded in integrated circuits (ICs) or designed into wearables and other small devices, to a variety of power conversion applications, up to grid-scale systems. This FAQ series will explore the versatility of switched-capacitors. Following this initial […]
