Abstract :
A new quadrature oscillator circuit using three multiple outputs second-generation current conveyors (CCIIs), two grounded capacitors and three resistors are presented. Two high output impedance current-mode signals and two voltage-mode signals each pair with 90deg phase difference are available in the proposed circuit. The oscillation condition and oscillation frequency are independently controllable through grounded resistors. The use of only grounded capacitors makes the proposed circuit ideal for integrated circuit implementation. Experimental results are also included
