Abstract
A system for providing on-chip voltage supply includes a plurality of local voltage regulators each including a first input, a second input, and an output; a transconductance amplifier connected with the local voltage regulators and configured to drive the local voltage regulators, including a first input, a second input and an output; a reference voltage source; and a plurality of transistors. The output of the transconductance amplifier is connected to the first input of each local voltage regulators. The first input of each local voltage regulator is connected to ground through a first capacitor. The output of each local voltage regulator is connected to gate of each transistor correspondingly. Source or drain of each transistor is connected to a load, to the second input of the local voltage regulator, to each other through a plurality of first resistors representing metal routing resistance, and to ground through a RC network.
