  • Patent number: 10454369
    Abstract: A switched voltage converter may be controlled with load current feedforward control loop in addition to an output voltage feedback loop. The converter includes a first switch device that is controlled to open and close at a selected switching rate with a selected duty cycle. The first switch device is coupled in series with an inductor and conducts current through the inductor while the first switch is closed. A second switch device conducts current from the inductor to an output capacitor and to load while the first switch is open to produce an output voltage and a resulting load current through the load. The load current is measured in a continuous manner and a load current feedforward control signal is generated that is representative of the load current. The switch rate and/or duty cycle of the first switch is adjusted in response to the load current feedforward control signal.

  • Patent number: 10453738
    Abstract: Techniques of fabricating shallow trench isolation structures that reduce or minimize the number of trench cones during the formation of shallow trenches. The disclosed techniques introduce separate etch steps for etching shallow trenches with small feature dimensions and for etching shallow trenches with large feature dimensions. As an example, the disclosed techniques involve etching a first shallow trench in a first region of a substrate with a first etching parameter, and etching a second shallow trench in a second region of a substrate with a second etching parameter different from the first etching parameter. Among other things, the etching parameter may include an etching selectivity ratio of silicon to an etch retardant that contributes to cone formations. Because of the separate etch steps, the disclosed techniques allow the sidewall slopes between the first and second shallow trenches to be within a few degrees of deviation.
