A. Fabre et M. Alami, INSENSITIVE CURRENT-MODE NOTCH FILTER IMPLEMENTED FROM TRANSLINEAR CONVEYORS, International journal of electronics, 74(5), 1993, pp. 735-739
A filter-core operating in current mode and implemented from four pass
ive components in conjunction with two current conveyors is described.
It involves four second-order transfer functions which include a lowp
ass and a bandpass. A band reject is then obtained by adding two curre
nt followers to combine the output currents. Simulated results which c
onfirm the theoretical analysis are discussed. The conveyors are imple
mented in a translinear form.
