  • Rise and Fall Time Mismatch Adjustment Circuit for USB-On-The-Go Modules
    Publication number: 20190280679
    Abstract: An apparatus may include an output pin, an output driver circuit communicatively coupled to the output pin and configured to output a rising signal or falling signal on the output pin, and a programmable current source communicatively coupled to the output driver circuit. The programmable current source may be configured to drive a speed of a rising signal or of a falling signal on the output pin and, based upon adjustment data, increase or decrease current to the output driver circuit to change the speed of the rising signal or of the falling signal on the output pin.

  • Phase lock loop lock indicator
    Patent number: 9577650
    Abstract: A lock-on detection circuit for a phase-locked loop includes circuitry configured to receive first up and down outputs and second up and down outputs from one or more phase detectors and to determine from the first up and down outputs and the second up and down outputs how well the phase-locked loop is locked on to a reference clock.

  • USB regulator with current buffer to reduce compensation capacitor size and provide for wide range of ESR values of external capacitor
    Patent number: 9471074
    Abstract: A voltage regulator has a large gm current buffer driver added between a first stage of an operation amplifier and a last stage power transistor. This current buffer allows a significant reduction in the maximum internal and external compensation capacitances needed for regulator stability. The current buffer compensation circuit allows a wide range of external capacitor sizes that increases the flexibility in choosing the external capacitor types (with low to high ESR ratings).
