摘要： A semiconductor device having an on-chip voltage regulator to control on-chip voltage regulation and methods for on-chip voltage regulation are disclosed. A semiconductor device includes a circuit positioned between a ground bus and a power bus. A power switch array is positioned between the circuit and one of the ground bus or the power bus to generate a virtual voltage across the circuit. A monitor is positioned between the ground bus and the power bus. The monitor is configured to simulate a critical path of the circuit and to output a voltage adjust signal based on an output of the simulated critical path. A controller is configured to receive the voltage adjust signal and to output a control signal to the power switch array to control the virtual voltage.
