Abstract
This paper presents the design and implementation of a Low-Intensity Pulsed Ultrasound (LIPUS) generator for dental tissue regeneration. It consists of a power supply subsystem, an ultrasonic transducer, an impedance-matching circuit and an integrated circuit consisting of digital controller circuitry and driver circuit. The integrated circuit was designed and fabricated using 0.8µm High-Voltage Technology from Dalsa Semiconductor Inc. The power supply sub-system and impedance matching network are implemented using discrete components. Upon construction, the LIPUS generator was verified to function correctly and is capable of producing LIPUS power upwards of 100mW in the vicinity of the transducer';s resonance frequency. Power efficiency of the circuitry, excluding the power supply sub-system, is estimated at 70%.
