In nature, some species mate according to their phenotype similarity. The Assortative Mating Genetic Algorithm (AMGA) mimics some mechanisms of reproduction in natural environments. The main difference between AMGA and the Standard GA (SGA) is the selection of the parents in the crossover operators. We develop a similarity measure for the Vector(More)
This paper presents niGAVaPS (non-incest Genetic Algorithm with Variable Population Size), a genetic algorithm that mimics some mechanisms of evolution in natural environment populations. It prevents incest by forbidding the recombination of closely related individuals, based on their ancestry. The degree of ancestry considered is adjustable, niGAVaPS tunes(More)
– This paper presents a 14-bit 1.5 MSample/s two-stage algorithmic ADC with a power-and-area efficiency better than 0.5 pJmm 2 per conversion. This competes with the most efficient architectures available today namely, ΣΔ and self-calibrated pipeline. The 2 stages of the ADC are based on a new 1.5-bit mismatch-insensitive MDAC and simulations demonstrate(More)
