DXCCII based mixed-mode three phase oscillator

A mixed-mode three phase sinusoidal oscillator (MTSO) employing Second Generation Dual-X Current Conveyor (DXCCII) as the active element is presented. A feedback scheme consisting of two lossy integrators followed by a lossless inverting integrator is employed to obtain three voltage-mode and three current-mode sinusoidal signals simultaneously. The oscillation conditions and oscillation frequencies are independently controllable. The use of grounded passive elements ensures viability for monolithic integrated circuit implementation. Results of PSPICE simulations confirm the proposed theory.
