Automatic Evolutionary Oscillator Design


More than 18 new oscillators invented automatically, which equal or better the state of art, are SPICE validated and useful for practical design.

HUMIES Entry Text

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. (Paper under preparation)
