摘要


以電流式主動元件設計類比電路已被證實具有較低的功率損耗、較低的供應電壓、較高之頻寬、較大之線性及動態範圍等優點,因此有許多的類比電路以電流式主動元件來實作。 在本論文,我們主要的研究重點,是以第二電流傳輸器(CCII)做為電流式主動元件來建構一萬用混合式濾波器。濾波器電路使用了5 顆CCII、7 顆電阻與2 顆接地電容,用以實現低通、高通、帶通與帶拒之濾波功能。因為是混合模式濾波器,電路可以有輸入電壓或是電流,輸出亦可以是電壓或電流。 濾波器電路採用台灣積體電路公司零點三五微米互補式金屬氧化物半導體製程與HSPICE 模擬軟體,電源電壓為±1.65V,參數 w0與w0/Q 可以獨立調控。模擬結果頗近似於理想模式,而模擬結果與理想模式的差異是因為匹配阻抗與使用簡化模型的關係。

It has been verified that analog circuits designed by the current-mode active components have the advantages of low power consumption, low-suppy voltages, higher signal bandwidth, greater linearity, and large dynamic range. Therefore, at persent, there are many analog circuits realized by the current-mode active components. In this thesis, we aim at constructing a universal mixed-mode biquad filter by employing second-generation current conveyors (CCIIs) as the current-mode active components. The filter circuit uses five CCIIs, seven resistors, and two grounded capacitors to realize lowpass, highpass, bandpass, and notch. Because of the mixed-mode filter, the circuit can have input currents and/or voltages and output currents and/or voltages. The biquad circuit used TSMC 0.35μm CMOS process plus HSPICE simulation with a power supply of ±1.65V. The parameters w0
