Every great active filter has a carefully selected operational amplifier to create an optimum solution. Understanding the relationship between the filter’s quality factor (Q), circuit gain (G), and ...

This application note presents the design and analysis of a passive LC filter. It briefly describes the use of measurement-based model for design and analysis, as well as the modeling filter behavior ...

This paper presents a generalization of the Remez multiple-exchange (ME) algorithm for solving complex Chebyshev approximation by polynomials on the unit circle. The difficulties of implementing the ...

Low pass filter (3rd order Chebyshev filter) is based on the gyrators with cut-off frequency adjustment in wide range. There are two modes for cut-off ...
