摘要：A circuit that detects the power supply voltage requirement of each voltagedomain in an IC includes 1) a ring oscillator in each voltage domain, and 2) a powermodule. Two different circuit implementations of the power module may provide a

precise reference voltage to on-chip voltage regulators (LDO or DC-DC switching buckconverter). The power module supports DVFS and can provide the desired power supplyvoltage for advanced CMOS technology nodes (45 nm and beyond) in less than 100 ns.The voltage detection circuit clamps the voltage to the desired level to address powersupply voltage variations due to PVT and ageing. The proposed technique has minimalpower and area overhead to compensate for the power supply voltage variation, thusreducing power supply voltage margins which yields higher power saving.
