Zusammenfassung:This paper proposes an on-chip dc-dc converter for a fine grain IP-level DVS. Linear and switching regulators are compared considering this particular application. The chosen buck converter operates with the I/O power supply and uses two discrete devices, a capacitor and an inductor. A test design adaptable to the various operation modes of a logic block is described. Simulation results of the proposed dc-dc converter demonstrate that the maximum power efficiency is over 90% and the leakage current is reduced down to 84 nA.
