An approach to the optimization of the Ackerberg-Mossberg's biquad circuitry

Abstract

This paper describes a perspective approach to the electrical circuits design based on the utilization of the evolutionary algorithms. In order to show an example of how the devices of a circuit being described by a mathematical model can be determined, a low pass filter design was chosen, employing the circuitry consisting of two integrators in a feedback loop operating as a filter realizing a general biquadratic function. The modified Ackerber-Mossberg's topology was used. In the paper not only the results of the optimisation but also the results of simulation of the designed circuits are provided, including the sensitivity analysis.
