Abstract
High-voltage pulse train excitation for ultrasonic transducers offers exceptional signal-to-noise ratio (SNR) and enables the possibility of beamforming. Conventional high-voltage pulses cannot be directly generated from low-voltage batteries without a high-voltage source, requiring conversion to high-voltage DC before being shaped into pulses. Recent advancements in resonant pulser circuit architectures have made it feasible to convert low-voltage battery power directly into high-voltage pulses. However, these designs are limited to producing a single half-sine pulse. This work proposes a novel circuit architecture based on a 180nm BCD process, aiming to further enhance the performance of resonant pulsers and enable the generation of pulse trains.
