Abstract :
This comment relates to a previously published letter (see M.T. Abuelma´atti, ibid., vol.32, pp.1457-8, 1996) which presents a cascadable universal current-mode second-order filter using a single four-terminal floating nullor (FTFN) with low active and passive sensitivities. In it, the authors suggest an amended expression for the current-transfer function
