Current balancing, current sensor, and phase balancing apparatus and method for a voltage regulator

An apparatus comprising

• a bridge comprising a high-side switch and a low-side switch coupled in series with the high-side switch;
• a driver coupled to the bridge to drive the high-side switch and the low-side switch;
• a wave generator to generate a signal between a high threshold and a low threshold;
• a mixer coupled to the wave generator, wherein the mixer is to mix the signal from the wave generator with one or more currents indicative of an error;
• and
• a comparator coupled to an output of the mixer, wherein an output of the comparator drives the driver.

A system comprising:

• a memory;
• a processor circuitry coupled to the memory, the processor circuitry to execute instructions;
• and
• an antenna communicatively coupled to the processor circuitry, wherein the processor circuitry includes a DC-DC converter which comprises:
• a bridge comprising a high-side switch and a low-side switch coupled in series with the high-side switch;
• a driver coupled to the bridge to drive the high-side switch and the low-side switch;
• a wave generator to generate a signal between a high threshold and a low threshold;
• a mixer coupled to the wave generator, wherein the mixer is to mix the signal from the wave generator with one or more currents indicative of an error;
• and
• a comparator coupled to an output of the mixer, wherein an output of the comparator drives the driver.
