Synthesis of a Universal Biquadratic Transimpedance Filter

萬用雙二階轉阻濾波器之合成

摘要


此篇論文提出一個使用電流傳輸器的萬用雙二階轉阻濾波器,它由一個雙輸出電流差分緩衝放大器,一個正型差動差分電流傳輸器、電流回授放大器和一個正型第二代電流傳輸器所組成。此濾波器使用四種電流傳輸器以及接地電阻和電容來實現低通、高通和帶通響應,並已用HSPICE驗證此篇論文所提出之分析。

This paper presents the synthesis of a universal biquadratic transimpedance filter using current conveyors. One is constructed with a multi-output current differencing buffered amplifier (MOCDBA), a positive type differential-difference current conveyor (DDCC+), a current feedback amplifier (CFA) and a positive type second-generation current conveyor (CCII+), to eliminate the redundant terminals. The filter employs four types of active device with grounded resistors and grounded capacitors to realize the lowpass, highpass and bandpass responses. Hspice simulations confirmed these analysis in this paper.
