What This Document Is
These are subject notes from ELENG 247A, Introduction to Microelectromechanical Systems, offered at the University of California, Berkeley. Specifically, this material focuses on the design and analysis of filters within the context of MEMS systems. It delves into the core building blocks used to create these filters and how their characteristics impact overall performance. The notes represent a focused lecture covering integrator-based filter designs.
Why This Document Matters
This resource is invaluable for students enrolled in an introductory MEMS course, particularly those concentrating on analog circuit design and signal processing. It’s most beneficial when studying filter topologies, active filter implementation, and the challenges of building high-performance filters at the microscale. These notes will support your understanding of lecture material and provide a reference point for assignments and exam preparation. Understanding these concepts is crucial for anyone aiming to design and implement sophisticated MEMS devices that require precise signal conditioning.
