SUMMARY

The discussion centers on designing a 6th order Butterworth Anti Alias Filter (AAF) using a 2nd order Sallen & Key topology. Participants emphasize the necessity of demonstrating prior work on Sallen & Key filter configurations before receiving assistance. Key considerations include determining the number of operational amplifiers (op-amps) required and the appropriate polynomial form for the filter design.

PREREQUISITES
  • Understanding of Sallen & Key filter topology
  • Knowledge of Butterworth filter design principles
  • Familiarity with operational amplifier (op-amp) configurations
  • Basic skills in polynomial mathematics for filter design
NEXT STEPS
  • Research the design of 6th order Butterworth filters
  • Learn about Sallen & Key filter configurations and their applications
  • Explore operational amplifier selection criteria for filter design
  • Study polynomial forms used in filter design and their implications
USEFUL FOR

Electrical engineers, students in signal processing, and anyone involved in designing analog filters will benefit from this discussion.

Hi guys,

please help me this problem.
A certain application requires a 6th order Butterworth type Anti Alias Filter (AAF). The configuration in 2nd order Sallen & Key Filter is to be used and carry out a component level design of the filter.

Welcome to the PF, pavvi59. We do require that you show some of your own work before we can offer tutorial help. So what can you show us about Sallen & Key filter topologies? How many opamps will be required to make a 6th order filter? What polynomial form will you need to use?
