With a total of 3 patents to his name, his work has had a considerable impact on power management technologies.
Latest Patents
One of Wenjun Yun's latest patents focuses on current sensing in an on-die direct current-direct current (DC-DC) converter for measuring delivered power. This invention describes a DC-DC converter that efficiently converts input voltage to output current at an output voltage coupled to a load circuit. The design includes a high side driver (HSD) circuit to drive the output current in the first stage, and a low side driver (LSD) circuit to couple the power output to a negative supply rail (GND) in the second phase, with output current being periodic. The DC-DC converter also features an amplifier circuit to equalize an output voltage and a mirror voltage. Based on the mirror voltage, the current sensing circuit generates mirror current that corresponds to driver current. This mirror current can be measured as a representation of the output current delivered to the load circuit. Furthermore, a plurality of these DC-DC converters can provide multi-phased current to the load circuit, enhancing power delivery efficiency.
