Abstract
A novel fully-differential (F-D) digitally adjustable current amplifier referred to as Digitally Adjustable Current Amplifier (DACA) and its application to the design of F-D filter working in the current mode are presented in this contribution. The basic features of DACA are shown. The filter was designed by the transformation of the single-ended (S-E) structure and is universal. The parameters of the filter can be easily tuned thanks to properly placed DACA elements. Simulation results are included in the contribution.
