Realization of Resistorless Wave Active Filter using Differential Voltage Current Controlled Conveyor Transconductance Amplifier
نویسندگان
چکیده
In this paper, a resistorless realization of high order voltage mode wave active filter based on differential voltage current controlled conveyor transconductance amplifier (DVCCCTA) is presented. The wave method is used for simulating reflected and incident wave for basic building block i.e. series inductor and configuring it for other passive element realization by making appropriate connection. The proposed structure uses grounded capacitors and possesses electronic tunability of cutoff frequency. The proposed approach is verified for a 4 order low pass filter through SPICE simulation using 0.25 μm TSMC CMOS technology parameters.

Abstract: A new electronically tunable mixed-mode biquadratic filter with three current controlled current conveyor transconductance amplifiers (CCCCTAs) and two grounded capacitors is proposed. With current input, the filter can realise lowpass (LP), bandpass (BP), highpass (HP), bandstop (BS) and allpass (AP) responses in current mode and LP, BP and HP responses in transimpedance mode. With v...
