An implementation of current-mode multiphase sinusoidal oscillators is presented. Using CCCCTA-based lossy integrators, odd and odd/even phase systems can be realised with following advantages. The condition of oscillation and frequency of oscillation can be electronically/orthogonally tuned. The high output impedances facilitate easy driving an external load without additional current buffers. The proposed MSOs provide odd or even phase signals that are equally spaced in phase and equal amplitude. The circuit requires one CCCCTA and one grounded capacitor per phase without external resistor and additional current amplifier. The effects of the non-idealities of the CCCCTA-lossy integrator sections were also studied. The results of PSPICE simulations using BJT CCCCTA are included to verify theory.
