Abstract
A wireless system includes a radio and a voltage regulator, which provides a supply voltage to the radio. The voltage regulator includes a storage element, at least one switch that is coupled to the storage element and a controller. The controller operates the voltage regulator in a continuous mode of operation, operates the voltage regulator in a discontinuous mode of operation in response to an output current of the voltage regulator decreasing below a predetermined threshold; operates the switch(es) to energize the storage element in response to a detection of whether an output voltage is below a threshold level; operates the switch(es) to halt the energization of the storage element in response to detecting a current in the storage element reaching a predetermined current threshold; operates the switch(es) to energize and de-energize the storage element in the discontinuous mode of operation; and operates the switch(es) to energize the storage element in synchronization with a periodic clock signal.
