Abstract

A new filter circuit is proposed for the realisation of nth-order lowpass current-mode transfer function with unity gain by the active-RC circuit containing a minimum number of capacitors, n resistors and n+1 current conveyors. All of the current conveyors are either of the inverting or the noninverting type and they act as unity gain current followers. This makes the proposed circuit simple and attractive for current-mode operation.
