Multiphase sinusoidal oscillator using second-generation current conveyors

A multiphase sinusoidal oscillator using second-generation current conveyors is presented. The oscillator can generate n signals which are equal in amplitude and equally spaced in phase. The oscillation frequency of each phase is independently controlled by a grounded resistor, which makes it easy t...

Description
Summary:A multiphase sinusoidal oscillator using second-generation current conveyors is presented. The oscillator can generate n signals which are equal in amplitude and equally spaced in phase. The oscillation frequency of each phase is independently controlled by a grounded resistor, which makes it easy to convert into a voltage-controlled multiphase oscillator. The proposed circuit is suitable for IC fabrication because all the passive elements are grounded. Experimental results are given to verify the theoretical analysis.
