| Summary: | 碩士 === 中原大學 === 電機工程研究所 === 91 === Active RC circuits employing current-mode active elements have the following advantageous features, wider bandwidth, higher dynamic range, better linearity property, less power loss, and simpler network structure.One of the current-mode active elements, named current-controlled current conveyor, is widely used. The proper application of the intrinsic resistance in the X terminal of a CCCII makes it easy to simplify the network structure.
A new synthesis method of the nth-order voltage-mode all-pass filters by using the second-generation current controlled conveyors(CCCIIs) is proposed. The realized nth-order all-pass filter contains the least number of active and passive components compared with the recent filter structures. The employment of grounded capacitors makes it attractive for integrated circuit implementation.
