A circuit for driving ultrasound transducers uses a sample-and-hold circuit to sample multiple sample periods of a transducer driving waveform, and uses the samples to modify drive parameters. Use of multiple sample periods enables independent measurement and adjustment of different portions of the transducer driving waveform to ensure mirror symmetry.

Ultrasound transmitter

In at least some embodiments, an ultrasound system includes an ultrasound transducer and a bi-directional transistor coupled to the ultrasound transducer. The ultrasound system also includes an ultrasound receiver coupled to the bi-directional transistor. The bi-directional transistor operates to selectively connect the ultrasound transducer to ground and to selectively connect the ultrasound transducer to the ultrasound receiver.
