Abstract
An arrangement for providing a waveform for driving an ion mobility device. The arrangement comprises at least a plurality of switching circuits, each switching circuit comprising at least two switches operatively coupled to a first voltage source (VH), wherein the plurality of switching circuits is arranged to be coupled in parallel with respect to each other. The arrangement additionally comprises an interleaving circuit configured to receive a time-varying electrical input signal exhibiting an input frequency and based on said input signal, operate the plurality of switching circuits to provide a waveform via the switches, said waveform exhibiting a switching frequency that is essentially equivalent to the input frequency.
