High voltage ultrasound transmitter with symmetrical high and low side drivers comprising stacked transistors and fast discharge

摘要

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 driver and a bias network. The first driver includes a first plurality of drive transistors that when activated drive an ultrasound transmitter output to a first voltage. The first bias network is coupled to the first plurality of drive transistors, and, at least in part, controls distribution, across the drive transistors, of voltage at the ultrasound transmitter output. Control inputs of the first driver are decoupled from the ultrasound transmitter output.
