The dual mode charge pump can apply to a much wider input supply voltage range with less numbers of power switches, thus requiring less die area and lower costs. Moreover, the dual mode charge pump can precisely define a common mode voltage, thus making the common voltage drift smaller and less load dependent, especially when the output supply voltages are under different load conditions."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Dual mode charge pump","description":"A dual mode charge pump is operable in a first mode or a second mode for providing positive and negative output voltages that can be stabilized by adjusting the charging time of two terminals of a fly","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8487690","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.
