Local variations are increasingly important in new technologies. This paper presents the design of adaptive circuits based on the concept of Adaptive Body Bias Islands and a Forward and Reverse Body Bias Generator for FDSOI technology. The proposed Body Bias generator design, based on a DLL, allows a 70% area reduction compared to the DACbased conventional design and reduces local variability by 85%. This closed loop implementation also allows to track runtime variations.
