Combined novel addressing elements and HV-ESD Clamp protected for medical ultrasound system

In this paper, HV-ESD Clamp protected ultrasound transducer topology is proposed for driving multichannel medical ultrasound transducer array. High voltage power, low voltage logic and high voltage CMOS architecture were integrated in ultrasound chip. On-chip high voltage electrostatic discharge (HV-ESD) protection design in smart power technology of ultrasound chip is a challenging issue. Specially driving method is controlled spatially on the ultrasound transducer elements to avoid the strong interference between one and neighbor another one.
