A temperature characteristic of sensor sensitivity has a negative first order coefficient and a positive second order coefficient. The sensor drive circuit includes a first current source configured to generate a first current having a temperature characteristic of which a first order coefficient is positive. The sensor drive circuit includes a second current source configured to generate a second current having a temperature characteristic of which a first order coefficient is negative. The sensor drive circuit includes a first current calculator configured to add the first current and the second current to generate a third current."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Sensor drive circuit with improved temperature characteristic compensation","description":"A sensor drive circuit for driving a sensor with a current includes at least one circuit configured to generate a drive current for the sensor, the drive current having a reverse temperature character","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11525751","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.
