... synthesizer requirements imposed by cellular phone applications have been a key driver for PLL research. Design/methodology/approach This paper first opted to present the recent developments on implemented techniques of LC-VCO designs in popular RF bands. An LC-VCO with a differential (cross-coupled) MOS...
