Abstract:
Systems, methods, and devices that employ a dynamic gate boost component (DGBC) to generate a desired boosted gate voltage to facilitate controlling an enhanced charge pump are presented. An enhanced charge pump can comprise a desired number of charge transfer switches (CTSs) and a desired number of DGBCs, wherein a DGBC can apply a desired boosted gate voltage to the gate of an associated CTS to control switching of the CTS. An auxiliary gate boost component (AGBC) of one circuit path can apply a desired boosted gate voltage to a CTS of another circuit path to control switching of that CTS. The AGBC and DGBC can operate to facilitate maintaining the overdrive voltages of all of the CTSs in the enhanced charge pump so that the overdrive voltages are essentially unchanged under various loading current conditions. Multiple enhanced charge pumps can be cascaded to produce a higher output voltage.
