Abstract

Transmitters and waveform generators are provided for ultrasound imaging. Low-voltage transistors are connected in cascode with the high-voltage transistors used to generate the ultrasound pulses. The low-voltage transistors trim the high-voltage transistors, adjusting the drive strength of the high-voltage transistors. By trimming, the rise and fall time of the pulses generated by the high-voltage transistors may be more closely matched.
