A new universal filter configuration using a recently introduced active element, namely Current Differencing Buffered Amplifier is presented. Independent control over filter parameters, namely the natural frequency, quality factor and gain is achieved. The filter offers all the advantages of Current Differencing Buffered Amplifier, i.e. being free from parasitic capacitances, current-mode operation and simple implementation while keeping the compatibility with existing voltage-mode signal processing circuits. Detailed analysis of the non-idealities of the active element is included. Experimental results that verify the analytical results are included.
