This authoritative resource offers you comprehensive knowledge and detailed design guidance on active filters for integrated-circuit applications. The book identifies common problem areas, reviews circuit analysis operations, and thoroughly illustrates the concept of feedback. You learn the state variable procedure - a general design approach that is appropriate for a wide range of applications. The book also discusses classic approaches such as cascade and biquad circuits for comparative purposes. This unique resource features a case study for two operational amplifier designs that illustrates key challenges that need to be overcome. The book presents a multitone procedure for the simulated testing of switched capacitor designs, and teaches you how to find desired pre-corrected network functions that can be implemented to meet arbitrary specifications. Other key topics examined include sensitivity considerations, leapfrog architecture, and critical frequency distortion due to the switched capacitor integrator.
