摘要：

Design of an equivalent slew-rate monolithic pulse generator using bipolar-CMOS-DMOS (BCD) technology for medical ultrasound transmitters is presented in this paper. The pulse generator employs a floating capacitive coupling level-shifter architecture to produce a high-voltage (V-pp = 80 V) output. The performance of equivalent slew-rate in the rising and falling edge is achieved by carefully choosing the value of coupling capacitors and the size of the final stage high-voltage MOSFETs of the pulse generator. The measured output pulses show the rising and falling time of 8.6 nsec and 8.5 nsec, respectively with second harmonic distortion down to 40 dBc, indicating the designed pulse generator can be used for advanced ultrasonic harmonic imaging systems.
