Realization of Square Root Domain Filters from Passive Filters
نویسنده
چکیده
A simple design method is proposed for square root domain filters. The method is based on the imitation of passive filters (or their signal flow graphs). This allows square root domain topologies and parameters to be easily extracted. The method is augmented by a simple method to study and manipulate the filter’s DC point. The method is used to design a universal biquad filter as a demonstration of its applicability. Index Terms Square root domain, DC operating point, Universal biquad, ELIN filters By Karim O.

Class-AB Square-Root Domain Filters Based on the Floating
In this paper a new approach for design of class-AB current-mode square-root domain filters based on the electronically simulated translinear loop principle is presented. FG-MOS transistors that operate in strong inverted saturation region are employed for implementation of translinear loop circuit. The filter achieves immunity to body effect, low circuit complexity, large input dynamic ran...

The harmonic in distribution systems becomes an important problem due to an increase in nonlinear loads. This paper presents a new approach based on a graph algorithm for optimum placement of passive harmonic filters in a multi-bus system, which suffers from harmonic current sources. The objective of this paper is to minimize the network loss, the cost of the filter and the total harmonic disto...

متن کاملOptimal Sitting, Sizing, and Operation of Batteries and Passive Filters to Mitigate Over-voltage and Harmonic Problems in Distribution Networks with High Photovoltaic Penetration
Photovoltaic systems (PVs), despite their many advantages, may have effects such as power quality issues (voltage and harmonics increase), short-circuits level increase, protection issues, and transient stability for network. Some of these effects are due to the high PV penetration, which encounters the network with the over-voltage and harmonics problems. In this paper, the location, size and ...
متن کاملA New Approach for Current-Mode SRD Filters
In this paper a new geometric-mean circuit for current-mode square-root domain filters (SRD) is presented. The geometric-mean circuit employs MOSFET transistors that are operating in both strong inverted saturation and triode regions and works in low supply voltage. Simulation results by HSPICE confirm the validity of the proposed design technique.
