Voltage Mode Universal Biquad Using CCCII

الملخص EN

This paper proposes a multi-input single-output (MISO) second-order active-C voltage mode (VM) universal filter using two second-generation current-controlled current conveyors (CCCIIs) and two equal-valued capacitors.

The proposed circuit realizes low pass, band pass, high pass, all pass, and notch responses from the same topology.

The filter uses-minimum number of passive components and no resistor which is suitable for IC Design.

The filter enjoys low-sensitivity performance and exhibits electronic and orthogonal tunability of pole frequency (ω0) and quality factor (Q0) via bias current of CCCIIs.

PSPICE simulation results confirm the theory.
