Abstract
In start-up, current is sourced by a current source to a first plate of a first capacitor while a second capacitor is maintained at zero charge. In a subsequent first operating phase, current is sourced to a first plate of the second capacitor while a second plate of the first capacitor is connected to the first plate of the second capacitor. At the end of the first operating phase, the first capacitor is discharged. In a subsequent second operating phase, current is sourced to the first plate of the first capacitor while a second plate of the second capacitor is connected to the first plate of the first capacitor. At the end of the second operating phase, the second capacitor is discharged. Steady state operation of the circuit involves an alternation of the first and second operating phases interleaved with transition phases where the first and second capacitors are discharged.
