A CMOS High-Voltage Transmitter IC forUltrasound Medical Imaging Applications
Abstract-A CMOS High-Voltage Transmitter IC forUltrasound Medical Imaging Applications. A high-voltage (HV) transmitter integrated circuit for ultrasound medical imaging applications is implemented using 0.18-μm bipolar/CMOS/DMOS technology. The proposed HV transmitter achieves high integration by only employing standard CMOS transistors in a stacked configuration with dynamic gate biasing circuit while successfully driving the capacitive micromachined ultrasound transducer device immersed in an oil environment without breakdown reliability issues. < Final Year Projects > The HV transmitter including the output driver and the voltage level shifters generates over 10-Vp-p pulses at 1.25-MHz frequency and occupies only 0.022 mm2 of core die area.
