Abstract	A multiphase oscillator employing phase-setting and oscillation-generation units was developed for modern communication systems. The phase-setting unit includes multiple cascading phase-shifting cells the number of which determines output signal phase differences. The oscillation-generation unit consists of multiple oscillators to trigger the phase-setting unit. This configuration ensures that the proposed multiphase oscillator has good oscillation quality and high phase accuracy. In addition, a voltage-controlled ring oscillator capable of generating two oscillation signals with a phase difference of 180/spl deg/ is designed. It not only decreases the settling time of the multiphase oscillation system, but also reduces power dissipation due to its simplicity. By using TSMC 1P6M 0.18 /spl mu/m CMOS technology, the proposed multiphase voltage-controlled oscillator (VCO) yields oscillation signals ranging from 2.37 GHz to 2.53 GHz at a supply voltage of 1.8 V. There are 8 oscillation signals with phase differences of 45/spl deg/, 90/spl deg/, 135/spl deg/, 180/spl deg/, 225/spl deg/, 270/spl deg/, 315/spl deg/ and 360/spl deg/. Power dissipation is around 4.21 mW to 4.88 mW.
