Adaptive voltage scaling (AVS) is a well-known strategy to adapt the power supply to die-to-die and temperature variations [1]. However, AVS needs dedicated power supplies with nonnegligible overheads, e.g. extra die area, lower power converter efficiency, and with granularity limitations or complex fine-grain integration in the power mesh. SOI-based technologies offer unique features by biasing the wells below the transistors to tune the threshold voltage (VTH). The well-known adaptive back-biasing (ABB) technique has
