Voltage regulator circuitry including module for switching frequency self-optimization

An apparatus comprising:

• a summer to generate a sum of currents from respective current sensors of voltage regulators of an integrated circuit device;
• a unit to perform a comparison between a value of the sum and a selected value and generate digital information based on the comparison;
• and
• a frequency control block to receive the digital information to control a clock signal provided to each of the voltage regulators, wherein a frequency of the clock signal is based on a value of the digital information.

An apparatus comprising:

• conductive lines on a circuit board;
• an antenna coupled to the conductive lines;
• and
• a device coupled to the conductive lines, the device including:
• voltage regulators included in an integrated circuit device, each of the voltage regulators including a current sensor;
• a frequency control block to provide a clock signal to each of the voltage regulators, the clock signal having a frequency based on digital information;
• and
• a module to receive current information from the current sensor of each of the current sensors and provide the digital information to the frequency control block, the digital information having a value based on the current information from each of the current sensors.
