Power-Scalable Dynamic Element Matching for a 3.4-GHz 9-bit $\Delta\Sigma$ RF-DAC in 16-nm FinFET

This letter presents a hardware-efficient technique to scale the power consumption of dynamic element matching (DEM) DACs with the static back-off level of the digital input signal. Unlike previous DEM techniques, the proposed power-scalable approach disables parts of the DEM encoder and DAC elements when the digital signal level is decreased from full-scale, thus resulting in reduced power consum...
