The article deals with the power supply of the microcontroller core, which allows you to adjust the voltage to ensure the necessary balance between performance and power consumption of the system. When using this source, the core power supply voltage depends on the fill factor of the pulse-width modulated generator. These expressions allow you to adapt the proposed source for a microcontroller with an arbitrary power supply voltage.
