<p>A voltage regulator for use within an envelope tracking power supply system is described. The voltage regulator comprises a voltage regulation module. The voltage regulation module comprises at least one energy storage element, the at least one energy storage element comprising a first terminal operably coupled to a first node of the voltage regulation module, and a second terminal operably coupled to a second node of the voltage regulation module. The voltage regulation module further comprises an input arranged to receive a reference voltage supply signal, the input being selectively couplable to the first node and selectively couplable to the second node, an output selectively couplable to the first node and selectively couplable to the second node, and a ground plane selectively couplable to the second node.</p> |
