—A voltage-controlled oscillator (VCO) based on double cross-coupled multivibrator structure with a center frequency of 4.3 GHz and a tuning range of 2 GHz has been designed and implemented in standard 0.35-m BiCMOS technology. The measured phase noise is 113 dBc/Hz at 600-kHz offset frequency from the carrier. The VCO draws 14.6 mA from the 2.5-V supply.
—This brief presents a fully monolithic voltage-controlled os-cillator (VCO) based on double cross-coupled multivibrator architecture with a speed enhancing-load designed and implemented on a standard 0.35-m BiCMOS process. The tuning range achieved is greater than 1.6 GHz with a center frequency of 3.6 GHz and the measured phase noise is 98 2 dBc/Hz at an(More)
