The reference modules are mutually connected in parallel. Each reference module includes a reference capacitor and a reference switch connected in series. A plurality of reference capacitances of the reference capacitors are substantially identical. The reference switches are controlled by a plurality of control signals. The control signals are corresponding to a control code. The DAC produces an analog voltage according to the control code. An analog difference, between a first analog voltage corresponding to a first control code and a second analog voltage corresponding to a second control code, monotonically increases or monotonically decreases as a first value corresponding to the first control code increases. The first control code is consecutive to the second control code."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Nonlinear digital-to-analog converter","description":"A digital-to-analog converter (DAC) includes a plurality of reference modules, an output capacitor configured to output the analog voltage, and a sharing switch coupled between the output capacitor an","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11251802","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.
