The method further comprises applying a second local oscillator signal with an inverted polarity to a second subset of cells of the digital to analog conversion circuitry when a number of cells from the first subset of cells are used and selecting a number of cells from the second subset of cells to generate a second analog signal corresponding to the second input sample."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for operating radio frequency digital to analog conversion circuitry in the event of a first and a subsequent second input sample with different signs and an digital to analog conversion circuitry","description":"A method for operating a radio frequency digital to analog conversion circuitry with a number of cells if a first input sample and a subsequent second input sample have different signs, comprises gene","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9647678","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.
