Abstract :
In this paper, we present the design of fourth order filter structures by using the Operational Transresistance Amplifiers (OTRA). In this paper OTRA based second order low pass and high pass filter is verified and fourth order band pass and notch filter topologies are also obtained. The resulting filters are simulated by 0.18μm CMOS process through Orcad Unison Suite. The results of these filters are discussed and compared in terms of performance and frequency range.
