Title:
RECONFIGURABLE VOLTAGE REGULATOR
Document Type and Number:
WIPO Patent Application WO/2020/206633
Kind Code:
A1
Abstract:
A reconfigurable voltage regulator for use in a system having a multiple power domains includes a power detecting circuit and a charge pump. The power detecting circuit is coupled to a power supply and configured to partition a power range of the power supply into multiple voltages zones corresponding to the multiple power domains of the system and provide a pump enable signal associated with a specific power domain among the multiple power domains. The charge pump includes multiple pump stages arranged in a matrix, wherein each pump stage is activated or deactivated according to a corresponding bit of the pump enable signal.
