Claim Text:
1. A current generator comprising: a plurality of current cells connected in parallel, each current cell being connected to a switch; a first summer configured to sum an output of each current cell of a first subset of the plurality of current cells and a second summer configured to sum an output of each current cell of a second subset of the plurality of current cells; and a combiner configured to combine the outputs of the first and second summers, wherein each switch is switchable according to a sequence to generate a summed output of the current cells at a plurality of quantization levels to generate positive and/or negative alternations of a pseudo-sinusoidal, alternating current, wherein each current cell of the second subset of the plurality of current cells comprises a current sink, wherein each switch of the current cells of the second subset of the plurality of current cells is switched according to the sequence to generate a summed output of the current cells of the second subset at a plurality of quantization levels to generate the negative alternations of the pseudo-sinusoidal, alternating current.
