An Amplitude-Tunable Bipolar High-Voltage Pulser Using a Unipolar Supply for Ultrasound Applications

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...
