Abstract
A device includes a plurality of digital-to-analog converters (DACs), a multiplexer, a plurality of electrodes including a first electrode, and a plurality of direct current (DC) offset circuits including a first DC offset circuit. At least one of the plurality of electrodes is located along a lane for movement of an ion. The multiplexer has multiple inputs coupled to the plurality of DACs and multiple outputs including a first output. The first output is configured to provide a first voltage. The first DC offset circuit is coupled between the first output and the first electrode. The first DC offset circuit is configured to add a first DC offset voltage to either the first voltage or the first voltage amplified by a first gain. The first DC offset voltage is configurable.
