This thesis discusses the architecture, circuit implementation and simulation results of an amplitude-tunable bipolar high voltage (HV) pulser for ultrasound imaging. This design is capable of providing a relatively high-resolution amplitude modulation and allows bipolar pulsing under a unipolar supply with a small die size.<br/>The pulser...

Miniature ultrasound probes increasingly employ ASIC that drive the transducer elements with HV pulses and process the received echo signals. Due to size constraints, the HV pulsers tend to be relatively simple circuits, in which HV MOS transistors pull the transducer element to a HV supply and back to ground. An important disadvantage of...
