Limitations on active‐ R filter pole displacements are studied. the maximum magnitude of the natural frequencies is presented as a function of the op. amp. GB. Structures to realized biqads with two op. amps. and a predistortion technique, to take into account the amplifier's high frequency pole, are proposed. Experimental results are presented which confirm the theory.
