CPC H02M 1/008 (2021.05) | 20 Claims |
1. An apparatus, comprising:
a primary voltage regulator circuit configured to generate a primary supply voltage on a primary power supply node;
an integrated circuit including a plurality of functional blocks coupled to a plurality of local supply nodes; and
a plurality of bypass regulator circuits configured to source a plurality of bypass currents to the plurality of local supply nodes, wherein:
the integrated circuit further includes a plurality of local voltage regulator circuits including a particular local voltage regulator circuit configured to source, using the primary supply voltage, a supply current to a corresponding local supply node of the plurality of local supply nodes in response to a determination that a voltage level of the corresponding local supply node is less than a threshold value, and
the particular local voltage regulator circuit includes a low-dropout regulator circuit coupled between the primary power supply node and a given functional block of the plurality of functional blocks.
