- 中文摘要: 本文完成了一個新型全功能電壓模式的二階濾波器電路。此一電路包含了五個電流迴授運算放大器、兩個接地電容器、三個接地電阻器、以及三個浮接電阻器。它可以在不更換任何被動元件的情況下提供典型的濾波器功能,如低通、高通、帶通、帶阻(notch)、以及全通等。此一雷路也具備下述諸項優點:工作頻率及頻寬可以用接地電阻單獨控制,低輸出阻抗,低靈敏度(對主動元件與被動元件皆然)。
- 英文摘要: A new universal voltage-mode second-order filter circuit is presented. The circuit uses five current-feedback operational amplifiers, two grounded capacitors, three grounded resistors and three floatingresistors. The circuit can realize all the standard filter functions, lowpass, highpass, bandpass, notch andallpass,without changing the passive elements.The proposed circuit enjoys independent grounded-resistance-control of the natural frequency and the bandwidth, low output impedances, and low active andpassive sensitivities.
