Abstract
The circuit topologies are proposed for realizing the continuous time current-mode ladder filter of any order. The derived technique is based on the attractive features of the leapfrog simulation implementing using only multi-output second generation current controlled conveyor (MCCCII) and grounded capacitors that lead to simple structure, easy to design and suitable for IC fabrication. An example of the third-order elliptic low-pass filter which retains a minimum requirement of passive and active elements, as well as, possess the advantage of electronically tunable in cut-off frequency has been introduced. Moreover, this method can also be implemented by adding floating capacitors to the relative all-pole filter. Simulation results are provided to compare against the prototype passive RLC filter. © 2004IEEE.
