Design of current-mode sinusoidal quadrature oscillator using CCCHs

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.
