Beschreibung
Zusammenfassung:	Methods produce IC devices that include a multiplexor that is electrically connected to a bandgap reference generator and a charge pump. The multiplexor receives voltage levels of a voltage-boosted clock signal being output by the charge pump to the bandgap reference generator. The multiplexor outputs, to the charge pump, either: a retry signal (if the voltage levels of the voltage-boosted clock signal being output by the charge pump are below a voltage threshold) or a pump signal (if the voltage levels of the voltage-boosted clock signal being output by the charge pump are not below the voltage threshold). The pump signal causes the charge pump to output the voltage-boosted clock signal to the bandgap reference generator. The retry signal causes the charge pump to not output the voltage-boosted clock signal to the bandgap reference generator, and instead to precharge the charge pump.
