Exploiting Fully Integrated Inductive Voltage Regulators to Improve Side Channel Resistance of Encryption Engines

“…Exploiting inductive IVRs for PSCA protection requires integration of the IVR in the same process node as the digital circuits. Due to the usage of low passives, IVRs potentially can achieve a higher bandwidth, provided that the IVR controller is not limiting the bandwidth [88,41,1,54,52,53,42]. At advanced process nodes which are optimized for digital operations, designing high bandwidth analog PWM controller is challenging.…”
