Abstract :
The paper discusses the design of a fully integrated 0.35 μm BiCMOS frequency synthesizer, operating in the 4-to-5 GHz band. The circuit is suitable for wireless transceivers, providing carriers for both 802.11a (Europe and US) and HiperLAN transmission standards. Novel techniques for phase noise reduction are introduced, as well as enhanced approaches to VCO characteristics determination and frequency division circuitry.
