Abstract
An electrical waveform generating circuit has a programmable current source-driver. A digital switched current source is coupled to the programmable current source-driver and controlled by waveforms stored in the programmable current source-driver. A plurality of MOSFETs is coupled to the programmable current source driver. A center-tapped RF transformer is provided and has a primary coupled to the plurality of high voltage MOSFETs. A transducer is coupled to a secondary of the RF transformer.
