Auto Calibration Dead-Time Control Circuit

A method for controlling dead-time of a direct current to direct current (DC-DC) converter, the method comprising:

• providing an output voltage of a DC-DC converter to a first transistor;
• determining, via a current sensing circuit comprising at least two transistors electrically coupled together, a control current based on a voltage of the first transistor;
• determining, via a digital up/down counter, a delay count based on the control current;
• and providing the delay count to a delay cell.

A direct current to direct current (DC-DC) circuit comprising:

• one or more delay cells;
• a control circuit comprising a current sensing circuit having at least two transistors electrically coupled together, the control circuit further comprising an output electrically coupled to an input of the one or more delay cells configured to control the one or more delay cells;
• and
• a high side circuit and a low side circuit coupled to the one or more delay cells and configured to provide an output voltage, the high side circuit and the low side circuit each circuit comprising:
• a logic gate;
• one or more inverters;
• and
• a transistor,
• wherein the logic gate, the one or more inverters, and the transistor are electrically coupled together in series.
