该论文提出了一种双用低压差稳压器/电源门控电路，具有线性和开关导通模式，用于微处理器片上供电。它解决了多核处理器中不同单元需要不同供电电压且平台面积减小的挑战。
In recent generations of microprocessors, there has been an increase in the number and types of processors integrated on the same die. For example, in [1] several IA (Intel architecture) cores have been integrated on-chip with a graphics processor. Multi-core trends are expected to increase in future generations with different cores and units requiring varying supply voltages. As platform footprints are also required to decrease, this causes a unique challenge for voltage regulation. In [2], an on-die switching fully integrated voltage regulator (FIVR) was demonstrated, which presents a very good solution in many cases. However, the FIVR requires inductors, which may not always be available. In addition, it may be desirable to sub-divide some of the FIVR domains using power gates and/or linear voltage regulators, such as low-drop-out regulators (LDO). LDOs can be used to enable different units of the chip to operate at their
