| Summary: | 碩士 === 國立臺北科技大學 === 電腦與通訊研究所 === 101 === In recent year, biomedical and biological researches are vigorously growing.
The innovation of this stimulator is greatly considered a creative breakthrough in medication.
In this thesis, our purpose is to implement a implanted PRF stimulator. PRF stimulator is utilizing a coupling coil to realize a power transmission wirelessly, and the stimulator can deliver a PRF(Pulsed Radio frequency) waveform with 500KHz carrier frequency , 20ms stimulation duration, and it’s intensity is controlleable.
Owing to implantion of this stimulator inbody, the following problems must be encounterd and shall be solved:
1.The size of implanted stimulator must be much smaller, but it causes a difficult problem in IC testing.
2.Implanted-stimulator is overally covered by Parylene, so can be not observed its function by exterior surface.
In orde to solve these problems, a probeless IC testing system is designed. This system is operated by utilizing a coupling coil to realize a signal transmission wirelessly, and it can be divided into the transmitter part and receiver chip. In transmitter part,a Class-E power amplifier transmits energy and use IC U2207B to transfers the chip information. In receiver chip, it includes power management circuit, signal receiver, function generator, circuit under test, trasmitter and controller.
This system can test digital and analog signals,and then send the testing result which is packaged by logic controller back to the transmitter part wirelessly. The supply voltage of reciver chip is generated by photo diode and the measurement result shows the high feasibility of this system.
In this thesis, PRF stimulator and probeless IC Testing System are fabricated by TSMC 0.18 um 1P6M CMOS technology.
