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 driver and a second driver. Each of the drivers includes an N-type device and a P-type device. The N-type device and the P-type device of each driver are serially coupled. Activation of the first driver drives an ultrasound transmitter output to a first voltage. Activation of the second driver drives the ultrasound transmitter output to a second voltage. The driver activations produce an ultrasonic drive signal at the ultrasound transmitter output.
