摘要

This paper describes the design of a log-domain multiphase sinusoidal oscillator (MSO). The circuit is a direct realization of a first-order differential equation for obtaining the non-inverting and inverting lossy integrators. Each integrator comprises only a grounded capacitor and six transistors. The proposed MSO can be instantaneously controlled over wide frequency range by controlling the bias currents. The high-frequency of oscillation and oscillation condition can also be independently tuned which are indicated proposed MSO suitability in communications and high-frequency applications. The power consumption is obtained around 5.78mW at 100µA of bias current based on 2V single power supply. The oscillation frequency is controlled over four decades of frequency. The total harmonic distortion of four-phases (11.33MHz) is obtained around 1.12%.
