The trimming circuit is configured to trim the VCM, VREFP, and VREFN by adjusting a VC trim signal to increase the VCM until a VCM error is below a threshold; adjusting a high temperature trim signal to increase the VREFP and decrease the VREFN until a digital temperature signal associated with the digital-to-analog circuit attains a predetermined accuracy level for a first temperature; and adjusting a low temperature trim signal to increase the VREFP, VCM, and VREFN until the digital temperature signal attains a predetermined accuracy level for a second temperature."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Two way single VREF trim for fully differential CDAC for accurate temperature sensing","description":"A temperature sensing circuit of a data storage system includes a temperature sensor, a digital-to-analog circuit, and a reference generation and trimming circuit configured to generate a common mode ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11514990","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.
