Next, increase an oversampling ratio of parameters, to obtain a plurality sets of second performance results, and a plurality sets of second circuit specifications. Then, increase quantizer bit number, and increase attenuation quantity, to obtain a plurality sets of third circuit specifications. Finally, compare said first, second and third circuit specifications, to select one of greatest variation to perform calibrations."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Synthesis method of sigma-delta modulator capable of relaxing circuit specification and reducing power","description":"A synthesis method of Sigma-Delta modulator capable of relaxing circuit specification and reducing power consumption, comprising the following steps: firstly, set a target bandwidth and a target perfo","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8487798","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
