Abstract :
The paper addresses the design and realization of a high-frequency and wide range frequency synthesizer based on a PLL together with a varactorless LC-type VCO and a push-push frequency doubler. In addition, a high-speed programmable divider using multi-phase selection is employed for channel switching. The proposed circuits were fabricated in a standard 90-nm CMOS process with a chip area of 0.8×1.1 mm2. The PLL dissipates 60 mW at a 1.2-V supply. The measured phase noise of the doubler at 35.28-GHz frequency is -90.42 dBc/Hz at a 1-MHz offset.
