摘要：
This paper describes the design and experimental verification of a current-mode multiphase sinusoidal oscillator (MSO) employing current differencing units. The oscillator, composed of n 1st-order all-pass sections, generates harmonic current signals with 2n equidistant phase shifts, where n ≥ 2. Compared with conventional MSOs, this circuit is characterized by an extremely simple circuitry and a minimum number of passive and active components. The oscillation condition and the frequency of oscillation are orthogonally controlled. The proposed circuit is suitable for IC fabrication. Experimental verification on an erlier manufactured chip together with a detailed analysis of real influences are included in the paper.
