Abstract
An excitation circuit is disclosed which is responsive to a trigger signal to drive a capacitive load with a controllable high frequency pulse burst. The pulse burst takes the form of a multiple cycle output signal which has a selectively variable high voltage determined by the supply voltage of the circuit. The output signal replicates and is coherent with the trigger signal applied to the circuit. The latter signal thus determines the pulse width and signal duration, i.e. the number of cycles, of the output signal. The circuit is particularly adapted to provide a programmable burst excitation for driving an ultrasound transducer or the like.
