REALIZATION OF VOLTAGE MODE NOTCH FILTER BASED ON CURRENT DIFFERENCING TRANSCONDUCTANCE AMPLIFIER

In this study, a new voltage mode notch filter based on Current Differencing Transconductance Amplifier (CDTA), which is a recently common used active building block in analog signal processing applications, is presented. The proposed filter's performance has been evaluated by PSPICE. In simulation the MOSIS CMOS 0.35 mu m model parameters used for CMOS based CDTA. The simulation results show that the proposed filter has high performance in terms of working both at low and high frequencies. It was seen that the simulation results verified the theory. Also, the sensitivities of the passive circuit components are shown to be low.
