摘要: 本文提出了幾種用單塊電流傳輸器(CCII)實現(xiàn)的Q增強(qiáng)二階帶通濾波電路。這些電路使用的元件較已見報道的同類電路和用運算放大器(OA)實現(xiàn)的同類電路少;適當(dāng)選擇元件參數(shù),還可實現(xiàn)RCD串聯(lián)諧振器。

Abstract: This paper describes some new active bandpass filters using only a single second-generation current cenveyer (CCII), which are superior to early realizations for using fewer components. By choosing proper values of the circuit elements, they can be also used to simulate RCD series resonators. -
