There are two main purposes of the proposed structure. First, to achieve supply voltage less than diode voltage for ultra low voltage applications. Second, to increase efficiency through using DTMOS technique, without using MOS transistor and diode. At 1.3V input, the proposed converter provides 7.3% more efficiency when compared to the conventional DC-DC buck converter. The theoretical results have been confirmed by PSPICE using CMOS process technology. The obtained results show that DTMOS technique is an effective way for power converter designs and ultra low voltage and energy efficient applications. © 2023 IEEE.eninfo:eu-repo/semantics/closedAccessBuck converterMOSFET devicesThreshold voltageCMOS process technologyConverter circuitsDC-DC buck converterDiode voltageDynamic threshold voltage MOSFETsLow-voltage applicationsPower converter designSupply voltagesUltra low energyUltra-low-voltageEnergy efficiencyConference ObjectN/A
