Title

A CMOS RING OSCILLATOR VCO WITH QUADRATURE OUTPUTS AND HIGH-TUNING RANGE

Pages

  117-126

Abstract

 This paper presents the design of a new four-stage ring oscillator with QUADRATURE OUTPUTs using a 0.13mm CMOS 1P8M technology. The oscillator utilizes feed-forward technique and negative resistance to reduce the delay per stage and provides high frequencies. Employing single PMOS transistor to vary the load impedance allows reaching ultra-wide tuning range. The output frequency ranges from 0.8 to 11.3 GHz, which is equivalent to nearly 175% tuning range, while the circuit consumes only 10mW. Simulation results illustrate a PHASE NOISE of -83dBc/Hz @ 1MHz offset from centre frequency. Also, the worst case phase variation due to mismatch is better than 0.4o over the above frequency range.
