![]() If I understand correctly, it works like analog computer, using comparator as processing element and two capacitors as two analog memory cells, in which compared voltages are stored. It would be cool weekend project to build or to understand why it can' work. Question: Are there any fundamental issue to be solved with such type of ADC? Why there are no commercial products? or almost no papers about it? I've tried to simulate their circuit using LTSpice, but it is not working. Working principle is based on Bernoulli map computation. It is strange that such technique is not mentioned in any commercial products, and I only found one doctoral dissertation and one patent that uses similar technique, but it was hard to understand. To the best of authors’ knowledge, this could be the simplest ADC with less complicate components like opamps, comparators, digital decimation filters, DACs 824-827, doi: 10.1109/ICSAI.2012.6223136.Īccording to above discussion, we invent a novel ADC based on Bernoulli map, which is much different from any methodology of current ADCs. Liu, "Simple chaos-based ADC with only one opamp," 2012 International Conference on Systems and Informatics (ICSAI2012), 2012, pp. I found that successive approximation (SA) is probably easiest to build? I have FPGA to sample digital signals.Īlso, I found one exotic type: chaotic ADC. ![]() For educational purpose I am building 8-bit analog-to-digital converter, that is capable of audio frequency or low RF. ![]()
