Transform your design to an active inductor-less filter; use a Spice (or any other) simulation to verify that your circuit performs as desired. - Groups 1, 3, 5 and 7

Staring with your design, use a genetic algorithm to obtain a more economical design; use a Spice (or any other) simulation to verify that your circuit performs as desired. - Groups 2, 6, 4 and 8.
