A collector line which comprises a first current source connects to the high potential provider. An emitter line connects the common emitter to a low potential provider and comprises a second current source. The output is provided by or connected to the collector of the second bipolar switching device and provides said output voltage.A driving stage circuit applies a charge pump circuit driving signal across the bases of the bipolar switching devices and controls the charge pump circuit driving signal in accordance with a driving stage input signal. The driving stage circuit effects a shift of a DC operating point of the charge pump circuit driving signal as an increasing function of the output voltage function of the output voltage of the charge pump circuit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Charge pump apparatus, phase-locked loop, and method of operating a charge pump apparatus","description":"A charge pump comprises a charge pump circuit with bipolar switching devices with a common emitter.
