Abstract :
A low-power frequency synthesiser for mode-I UWB transceivers was fabricated in a 90 nm CMOS process. With proper frequency planning and single-sideband mixers, only one phase-locked loop is employed in the synthesiser. To reduce power consumption, low voltage operation circuit structures are used, and hence except for the VCO and dividers, the remaining building blocks can operate with a 0.5 V supply voltage, resulting in power consumption of only 9.8 mW.
