The method includes comparing a drain voltage of a current sink transistor of the charge pump with a drain voltage of a current reference transistor, and adjusting a gate bias voltage of the current sink transistor and the current reference transistor in a direction that reduces a difference between the drain voltage of the current sink transistor and the drain voltage of the current reference transistor. The method also includes comparing a common-mode voltage of a loop filter with a reference voltage, and adjusting a gate bias voltage of a current source transistor of the charge pump in a direction that reduces a difference between the common-mode voltage of the loop filter and the reference voltage."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Differential charge pump with extended output control voltage range","description":"One aspect of the present disclosure relates to a method for operating a charge pump.
