متن کاملRealization of Square Root Domain Filters from Passive Filters
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 demonstratio...

In this study, a new second order all-pass filter is synthesized in the square-root domain by using the statespace method. The proposed second order all-pass filter is constituted by current mirrors, current sources, currentmode square-root circuits and capacitors. The pole frequency of the filter can be tuned electronically by varying the values of the current sources of this circuit. The filt...
