Abstract
A system and method for providing a high voltage ultrasonic drive signal from an ultrasound transmitter are disclosed herein. An ultrasound transmitter includes a first plurality of drive transistors. A bias network is coupled to at least one transistor of the first plurality of drive transistors. A first switch is coupled to the bias network. The first switch selectively connects a first voltage to the bias network. The first switch is closed when generating an ultrasonic drive signal. The first switch is open when the transmitter is not generating an ultrasonic drive signal.
