The auxiliary and output current paths comprise second-current-mirror transistors connected so a second output current flowing along a second part of the output current path is dependent on the auxiliary current. The auxiliary current path comprises a control transistor connected in series with the first-current-mirror transistor of that path. The differential amplifier receives first and second input signals from nodes in the auxiliary and output current paths, respectively, and controls the control transistor with its amplifier output signal to control the drain or collector voltage of the first-current mirror transistor in the auxiliary path."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Charge pump circuitry","description":"Charge pump circuitry comprises a differential amplifier and parallel-connected reference, auxiliary and output current paths comprising first current-mirror transistors connected so an auxiliary curr","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10498231","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.
