Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY LTD.
Field: Electrical machinery, apparatus, energy (Electrical engineering)
Classification: CPC H | IPC H

Claim 14:
15. A direct current to direct current (DC-DC) circuit comprising:
one or more delay cells;
a control circuit comprising a current sensing circuit, a first transistor, and a digital up/down counter;
the control circuit further comprising an output electrically coupled to an input of 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;
wherein:
the first transistor is configured to be operational based on the output voltage and a gate voltage of the first transistor;
the current sensing circuit is configured to either modify or maintain a count of the digital up/down counter; and
the digital up/down counter is configured to modify or maintain a delay time of the one or more delay cells to minimize or eliminate the dead-time of the DC-DC circuit.
