| Summary: | 碩士 === 國立高雄應用科技大學 === 電子與資訊工程研究所碩士班 === 93 === The implementation of analog signal processing systems in the current domain offers the potential advantages of higher bandwidth capability, less circuit complexity, wider dynamic range, and higher operating speed. Consequently, current-mode approach has been accepted as an alternative mean besides the traditional voltage-mode circuits. It is playing an increasing important role in the development of many new high-performance circuits for signal processing application. In addition, current-mode active devices, which comprise voltage and current variables in their port relations of input and output, have been proved to possess favorable balance of operational flexibility and simplicity over their conventional op-amp counterparts. They are suitable to operate with signals in current-mode and in voltage-mode, rapidly gaining the acceptance of researchers as building blocks in high-performance circuit designs.
In this thesis, we proposed all of the current conveyor adjoint elements by using multi-output universal current conveyor. Two biquad filters and their dajoint filters also been proposed by using multi-output universal current conveyor as well as adjoint transform. The cascadability have been considered in the filters design, the filters have these advantages: less passive elements, low sensitivities and grounded capacitors that is very suitable for monolithic implementation. The Simulation result also verified with HSpice and TSMC 0.35μm 2P4M CMOS technology spice model.
