Abstract
Aspects of the present disclosure generally relate to methods and apparatus for continuous current sensing for a single-inductor multiple-output (SIMO) regulator. One example method includes operating a plurality of switches of the SIMO regulator, via a plurality of control signals, according to a plurality of switching states using a switching controller, sensing currents associated with at least a portion of the plurality of switches of the SIMO regulator using a plurality of current sense circuits, and selectively outputting a sense current from one of the plurality of current sense circuits based on a change in the plurality of controls signals occurring between a transition from a first switching state to a second switching state of the plurality of switching states.
