Original Abstract

A simple quadrature oscillator is proposed, based on the well-known two-integrator topology. Each integrator is employed by ZC-CG-CDBA (Z-Copy Controlled Gain Current Differencing Buffered Amplifier). The current gain is controlled digitally on the principle of R-2R current divider. The designed structure enables an independent control of the oscillation frequency and the oscillation condition. The designed circuit is manufactured with the utilization of commercial integrated circuits and its proper operation is demonstrated.
