Abstract

This paper presents a high voltage integrated circuit (IC) that has been designed for connection to a hybrid printed circuit board (PCB) in close proximity to a polyvinyldenefluoride (PVdF) high resolution transducer array. An array of 16 pulser channels has been fabricated on chip; each channel provides an output train of -100 V pulses of 25 ns width, and fall and rise times of 6.3 ns and 13 ns, respectively, with a capacitive load of 2 pF.
