Microprocessor die with integrated voltage regulation control circuit

A system comprising:

• an IC die which includes a microprocessor and a control circuit for a voltage regulator;
• and
• a plurality of power phase circuits, each of the power phase circuits including:
• a pair of field effect transistors (FETs) coupled in series between a power terminal and ground;
• an inductor coupled to a node at which the FETs are coupled to each other;
• and
• at least one driver coupled to the control circuit to receive a control signal from the control circuit, the at least one driver also coupled to at least one of the FETs to selectively activate the FETs;
• wherein:
• the control circuit includes a plurality of sensors,
• the microprocessor includes a plurality of sensor locations in the microprocessor,
• one or more of the sensors are located at each of said sensor locations in the microprocessor;
• and
• one or more of said sensors at said plurality of sensor locations are for reading one or more buffers and/or registers of the microprocessor.
