What This Document Is
These are class notes from Introduction to Microelectromechanical Systems (MEMS) – ELENG 247A at the University of California, Berkeley. The notes focus on the critical area of filter design within the context of MEMS systems, specifically exploring both continuous-time and switched-capacitor filter architectures. This material represents a core component of understanding analog circuit design principles as they apply to miniaturized systems. The notes appear to be from a lecture series dedicated to filters.
Why This Document Matters
This resource is invaluable for students enrolled in an introductory MEMS course, or those studying analog circuit design. It’s particularly helpful when you need a consolidated reference for filter topologies, design considerations, and transformation techniques. These notes would be most beneficial while working on assignments involving filter implementation, system analysis, or preparing for examinations on analog circuit design. Understanding filters is foundational for signal processing within MEMS devices, making this a key area of study.
