【 摘 要 】

References(7)In this paper, an all-digital Power Amplifier (PA) that is tunable and fully-integrated on chip using 0.18µm CMOS is presented. The PA is designed using all-digital output-connected inverters controlled by a multi-phase clock generated using a multi-stage phase interpolator. Experimentally, in addition to the advantage of being all-digital and tunable, the PA consumed around 0.03mW/MHz, which is less than power consumed in recently proposed designs.
