Abstract
This paper describes the design, simulation and experimental verification of a current-mode multiphase sinusoidal oscillator (MSO) consisting of current differencing unit (CDU). The oscillator, composed of n 1st-order allpass filters, generates harmonic signals with 2n equidistant phase shifts where n≥2. Compared with conventional MSOs, this circuit is characterized by a minimum number of passive and active components. The experimental verification with the help of commercial integrated circuits is included.
