Abstract
A double-conversion receiver for cable modem applications requires a wide-tuning-range VCO with low phase noise characteristics for the first LO generation. Achieving simultaneously low phase noise and large tuning range from a monolithic VCO is an exceptionally challenging task. The design aspects of wideband monolithic LC-VCO are tackled in this paper with the boundaries set by a 0.9-/spl mu/m SiGe HBT technology. Two dual-VCO implementations are presented and a method for buffering the VCO signal without loading the LC-resonator is proposed. Both simulation and experimental results are given.
