Abstract

This paper proposed a novel second-order versatile filter employing Current Controlled Current Differencing Current Conveyor (CCCDCC) and Multi-Output Operational Transconductance Amplifier (MO-OTA). The proposed filter has a SISO (Single Input Single Output) structure which can serve as low-pass, high-pass, band-pass band-stop and all-pass filter by changing the bias signals. Moreover, both of the frequency and amplitude of the filter can be adjusted electronically. The PSPICE simulation results of the proposed filter based on 0.25μm CMOS process are presented; the results show that the analysis method is valid and effective.
