A second terminal of the capacitor is selectively coupled between a fixed voltage node through a third electronic switch and an error signal input through a fourth electronic switch. A positive voltage source is coupled to the negative voltage output through a feedback network. A feedback amplifier having an error signal output, a reference voltage input, and a feedback input is coupled to the feedback network. A switch controller having a first clock output drives the first electronic switch and the third electronic switch, while a second clock output drives the second electronic switch and the fourth electronic switch."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"High efficiency negative regulated charge-pump","description":"A charge-pump circuit includes at least one flying capacitor stage having a capacitor with a first terminal selectively coupled between a negative voltage input through a first electronic switch and a","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8461910","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.
