<p>A switching circuit, comprising: a first node for receiving a first voltage; a second node (502) for providing an output; a third node for receiving a second voltage; a capacitance (506) coupled between the second node (502) and the third node; means for intermittently charging the capacitance (506) to provide a first output voltage from the second node (502); and a switch (501) connected between the first node and the second node (502) for isolating the second node (502) from the first node when open and for discharging the capacitance (506) to provide a second output voltage when closed.</p> |
