Original Abstract

The paper introduces a novel sinusoidal quadrature oscillator (QO) with low harmonic distortion. The oscillator utilizes the non-linear non-inertial principle for amplitude stabilization and thus a fast transition to 0 steady state oscillations should be accomplished. This feature makes the QO suitable for operation at very low frequencies. The oscillator operates in the current-mode and is is intended for low-voltage low-power applications. It employs only three active elements, ZCopy Current Inverter/Follower Transconductance Amplifiers (ZC-CITA/ CFTA), one of which provides automatic gain control (AGC). The proposed principle was experimentally verified.
