Automatic Evolutionary Oscillator Design
Won GOLD at HUMIES: HUMAN COMPETITIVE AWARDS 2006
More than 18 new oscillators invented automatically, which equal or better the state of art, are SPICE validated and useful for practical design.
VIDEO: Demonstrates a working prototype of a Differential Difference Amplifier (AD830) Based Oscillator invented by a genetic algorithm. This is the only voltage mode oscillator which combines the attractive feature of grounded capacitors, uses minimum components and can be implemented by a single discrete IC/active element.
