In this paper a full high-voltage transmitting cir- cuit aimed for capacitive micromachined ultrasonic transducers (CMUTs) used in ultrasound medical applications is designed and implemented in a 0.35 μm high-voltage CMOS process. The CMUT is single-ended driven. The design is taped-out and measurements are performed on the integrated circuit. The transmitting circuit is reconfigurable externally making it able to drive a wide variety of CMUTs. The transmitting circuit can generate several pulse shapes, pulse voltages up to 100 V, maximum pulse range of 50 V and frequencies up to 5 MHz. The area occupied by the design is 0.938 mm 2 and the maximum power consumption is 187.7 mW.
