In this paper, a Universal Biquad Filter is designed with the help of the XILINX FPGA tool. This paper presents concept of universal filter using the FPGA model. Analog filters are basically used in different types of signal processing applications mainly they are used in the designing of greater order filter structures. Biquad filter designing using XILINX is a suitable method of second order “Biquad” analog filter which is taken as a main filter in making of higher order filters. The behavior of Biquad filter makes it very unique in the design of various filtering circuits using various types of active elements because it gives very suitable results. In our proposed design Biquad filter is implemented using XILINX tool. The Biquad filter using the active type of elements, is so chosen as to get greater bandwidth, maximum speed and minimum power consumption since these parameters are major considerations in design of any filter circuit. The simulation results are validating and the layout of the Universal Biquad filter is also designed using XILINX TOOL.
