A simple predistortion algorithm and limits of predistortion

Predistortion is used in linear, active RC signal processing circuits to compensate for the pole shifts caused by the bandwidth limitations of op amps used. While there are several workable approaches to calculating necessary predistortion parameters, the procedure offered here is simpler than those offered previously. In addition, by means of graphs and examples, the limitations of this process are clearly determined so that the result is a process for which the limitations are known. It is observed that predistortion fails when the actual pole radius reaches about one-third of the ideal pole radius.
