臺灣博碩士論文加值系統

本論文之主要目的係設計一多功能波形產生器，應用於低頻超音波治療及藥物導入之超音波驅動系統，此晶片經由TSMC 0.35μm 2P4M製程技術下線完成，晶片面積為250μm X 150μm，操作電壓範圍為0～3.3V，經由量測結果可得知當輸入訊號一端為250KHz，另一端為5MHz時，晶片仍能工作。
本論文討論之電路包含有乘法器、電壓控制振盪器、積分器與濾波器等，詳細之工作原理將於論文中作探討，論文之最後為結論與展望，期能完成低功率與低電壓各類系統之應用，達至人機一體之理想。

The major objective of this thesis is to design a multi-function waveform generator for low frequency ultrasonic system application. The 250μm X 150μm chip size of multiplier has been fabricated using TSMC 0.35μm 2P4M process technology. The operation voltage of this chip is 0V～3.3V. The results of measurement show that the chip can work when input signals are 250KHz and 5MHz, espectively.
The multiplier, voltage control oscillator, integrator and filter are discussed in this thesis. The work principle of design will be detailed in this thesis. Finally, the conclusion and future work of the multi-function waveform generator will be used in the low voltage and low power system application.
