Abstract

Three different 1.2 μm CMOS ring oscillator type VCO architectures have been presented. The VCO´s are intended for the use as building blocks of digital radio frequency synthesizer. It is demonstrated that linear control and improved phase-noise performance can be obtained by employing circuit design techniques and time domain based circuit optimization. The measurements results indicate that the maximum oscillating frequency range from 460 MHz to 900 MHz, power dissipation (at 5 Volts) from 6.5 to 11.5 mW and phase-noise at a 100 kHz carrier offset in a range of -83 to -95 dBc
