Active polyphase filter analysis
Proceedings of 2010 IEEE International Symposium on Circuits and Systems, 2010This paper describes the analysis and design of active polyphase filters. Analysis for 1- and 2-stage filters are carried out in this paper with simplified transconductance models. Gain and stability, which differentiate the active and passive filters, are analyzed and presented as a function of the key design parameters of the transconductance element

A notch filter based active damping of llcl filter in shunt active power filter
2017 International Symposium on Power Electronics (Ee), 2017Shunt Active Power Filter (APF) is a custom power device applied in electric grid system in order to compensate harmonic currents generated by nonlinear loads. Shunt APF operates by firing power electronic devices of voltage source inverter (VSI) to produce the compensation currents. The VSI also generates high frequency switching ripple harmonics that

Approximating Fractional Filters With Analogue Active Filter Structures
2019 42nd International Conference on Telecommunications and Signal Processing (TSP), 2019To practically implement a fractional-order filter, an integer-order approximation has to be realised as either digital or analog electronic circuits. Several implementation methods exist, each of them revealing different advantages. This paper considers the performance of analog active filters got with two implementation methods.

Extended active optical lattice filters: filter synthesis
Journal of the Optical Society of America A, 2010In this paper, we study the synthesis of asymptotically stable filters from a unit cell of a two-dimensional tunable lattice filter architecture consisting of four four-port couplers and four waveguides containing semiconductor optical amplifiers. Upper bounds on the number of gains that will produce a filter with a priori prescribed poles, for a ...

Baseband Filters: Active RC Filters
2015In telecommunications, voice transmission is a primary service, where human voice occupies a spectrum from 300 Hz to 3.4 kHz. A baseband filter is used to pass this frequency band and reject all others. To realize these filters, the traditional networks used inductors, capacitors and resistors to perform analog functions.
