Realization of electronically controllable first-order current-mode allpass filter using CCCHs and its application

This article presents a resistorless current-mode first-order slip ass filter based on second generation current controlled current conveyors (CCCHs). The features of the circuit are that: the pole frequency can be electronically controlled via the input bias current: the circuit description is very simple, consisting of 2 CCCHs and single grounded capacitor, without any external resistors and component matching requirements. Consequently, the proposed circuit is very appropriate to further develop into an integrated circuit. Low input and high output impedances of the proposed configuration enable the circuit to be cascaded in current-mode without additional current buffers. The PSpice simulation results are depicted. The given results agree well with the theoretical anticipation. The application example as a current-mode quadrature oscillator is included.

This paper presents the design of current-mode quadrature oscillator using second generation current controlled current conveyors (CCCIIs) as active element. The oscillator has high output impedance, electronic and independent control on oscillation condition and on oscillation frequency. It consists of 3 CCCIIs, two grounded capacitors and one electronic resistor. The proposed circuit is suitable for integrated circuit (IC) architecture. PSpice simulation result is included to demonstrate the practicality of the oscillator circuit.
