  • Patent number: 11990474
    Abstract: A method of fabricating a semiconductor device includes forming a gate structure, a first edge structure and a second edge structure on a semiconductor strip. The method further includes forming a first source/drain feature between the gate structure and the first edge structure. The method further includes forming a second source/drain feature between the gate structure and the second edge structure, wherein a distance between the gate structure and the first source/drain feature is different from a distance between the gate structure and the second source/drain feature. The method further includes implanting a buried channel in the semiconductor strip, wherein the buried channel is entirely below a top-most surface of the semiconductor strip, a maximum depth of the buried channel is less than a maximum depth of the first source/drain feature, and a dopant concentration of the buried channel is highest under the gate structure.

  • Patent number: 8030911
    Abstract: A hybrid control circuit and method combine analog circuit and digital circuit to generate digital PWM signals for a multiphase DC-DC converter to generate an output voltage. For current balance control, analog current error signals are generated by the analog circuit from analog phase current signals of the multiphase DC-DC converter and then converted into digital current error signals for calculating the duties of each phase of the multiphase DC-DC converter. Therefore, fewer bit devices can be used to achieve precise current balance control and the size and cost of the circuit can be reduced.
