The direct evolution of hardware, thus far, has concentrated largely upon the design of small, feed-forward digital designs. In this paper, a procedure is described, and results of experiments discussed, for evolving analogue filters using integrator cell models based upon working programmable analogue VLSI cells developed by one of the authors. This, of necessity, involves using feedback interconnects and settings in the range 0.0 - 1.0 which represents, for each individual cell, the gain (ratio of output power to input power) of the integrator. Experiments are conducted in the direct evolution of low-pass filter systems, and the implications of the results discussed. The evolutionary model used is similar in structure to that described in the companion paper [7].
