Abstract

See full text

An electrical waveform generating circuit has a pair of Pulse Amplitude Controlled Switching Current Sources (PACS). A gate pulse driver circuit is coupled to an input of each of the pair of PACS for sending gate pulses for driving the pair of PACS. A digital-to-analog converter (DAC) circuit is coupled to the gate pulse driver circuit for controlling amplitudes of the gate pulses. A transducer is coupled to the PACS.
