Current Generator

A method for generating a current, the method comprising:

• switching a plurality of current cells, wherein each current cell is connected in parallel;
• summing an output of each current cell of a first subset of the plurality of current cells for generating positive alternations of the pseudo-sinusoidal, alternating current;
• summing an output of each current cell of a second subset of the plurality of current cells for generating negative alternations of the pseudo-sinusoidal, alternating current;
• combining the summations of the output of each current cell of the first subset of the plurality of current cells and the output of each current cell of the second subset of the plurality of current cells to generate a pseudo-sinusoidal alternating current;
• and
• wherein switching the plurality of current cells comprises switching each current cell 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.
