High-order Filters: LC Ladder Filters

This lecture covers the design and simulation of high-order LC ladder filters. It explores the motivations behind using LC ladder filters, methods for direct and indirect simulation, and impedance normalization techniques. The lecture also delves into the functional simulation and implementation of LC ladder filters using active-RC circuits. Examples of 3rd-order LP LC ladder filter simulations are provided, along with detailed signal flow diagrams and final active-RC implementations. The lecture concludes with a summary of Butterworth and Chebyshev filter approximations, as well as the design and implementation of active-RC and OTA-C filters for high-order applications.
