The main charge pump generates a charge current and a discharge current to a subsequent loop filter according to a UP signal and a DOWN signal. The replica circuit generates a first voltage in response to the current values of the first current source and the second current source of the main charge pump. The tracking circuit adjusts the current values of the first current source and the second current source of the main charge pump according to the first voltage and a second voltage, wherein the second voltage is in response to a voltage of an output node of the main charge pump."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Charge pump circuit","description":"A charge pump circuit includes a charge generation circuit, a tracking circuit, a replica circuit, and a main charge pump.
