Low power design for RF circuits

The paper presents low-power design strategies for RF circuits, such as PA, LNA, mixer, and VCO. The design strategies focus on not only the low energy consumption with reused bias current but also the small chip area for low spurious environment contamination. For the low-power design, some published literatures have been adopted the operation voltage from 3V down to only 0.2V, to save the dissipated dc power from tens mW to several hundreds of μW. Additionally, many design strategies and green figures of merit (GFOM) are also presented in this work, for the future green RF circuit design.
