| Summary: | 碩士 === 國立臺北科技大學 === 電子電腦與通訊產業研發碩士專班 === 96 === Using digital CMOS circuits to design CMOS circuits is more simple, more stable and more mature in technique. In this way, the execution of digital CMOS circuits is more and more welcomed than that of analog CMOS circuits. In fact, basically, analog CMOS circuits shares the same space with digital CMOS circuits for the following reasons: analog which takes the most important role; the chip area; and the performance of circuits.
The OPA of current-mode has advantages, such as larger bandwidth, lower power consumption and much more linearity compared with voltage-mode…etc. The advantages of FTFN contain all the advantages of OPA and even better than current mode’s OPA. Under mixed-modes (voltage and current modes), FTFN has much more flexibility. Accordingly, the thesis is based on FTFN to design filter and simulate in cirrent, voltage,transadmittance modes which includes LP、BP、HP and transimpedance mode which includes BP and HP. The circuits are implemented using TSMC 0.35μm CMOS process and using FTFN to simulate filter in HSPICE.
