30 GHz monolithic voltage-controlled oscillator with dual-modulus prescaler in SiGe bipolar technology

This paper presents an integrated circuit suitable for frequency synthesis. The circuit consists of a monolithic voltage-controlled oscillator operating up to 30.5 GHz with static divide-by-256/divide-by-257 dual-modulus prescaler and consumes 500 mW from the 5.3 V supply. It is manufactured in a pre-production 0.4 /spl mu/m/85 GHz SiGe bipolar technology.
