  • Patent number: 11290011
    Abstract: A power conversion apparatus includes: a power supply circuit, a load switch and a control circuit. The power supply circuit generates a first power. The load switch controls the power path from the power supply circuit to a load. The control circuit generates a switching control signal to control a conduction level of the load switch according to an enable signal. The control circuit controls a level of the switching control signal to soft start from a first level to a second level. During the soft start period, the switching control signal has plural waveform segments including a first waveform segment and a second waveform segment. A level variation speed of the first waveform segment is higher than a level variation speed of the second waveform segment. The first waveform segment level precedes the second waveform segment level.

  • Publication number: 20160209681
    Abstract: This disclosure provides devices, systems, and methods for reducing substrate warpage in a display device. In one aspect, the display device includes a device substrate and a cover substrate, where the device substrate includes one or more display elements and the cover substrate includes a device cavity extending partially through the cover substrate. At least one of the display elements may be sealed by a primary seal in contact with and between the cover substrate and the device substrate to define a device area. A dummy area outside of the device area may be defined between the primary seal and a secondary seal, where the secondary seal is also in contact with and between the cover substrate and the device substrate. The display device may further include a dummy cavity extending partially through the cover substrate in the dummy area.

  • Patent number: 7924209
    Abstract: A self-calibration circuit and method for capacitors are provided. A capacitor array is calibrated to approximate a reference capacitor according to an average parameter generated by calibrating the capacitor array multiple times. Since the capacitance of the compensation capacitor required to be connected to the target capacitor in parallel is determined according to the average parameter generated by performing the calibration multiple times, the error caused by a single calibration can be reduced, and meanwhile the calibration error caused by a reference voltage error or noise is reduced.

  • Patent number: 7906952
    Abstract: A voltage regulator includes a comparator, a first voltage output unit, a second voltage output unit, a third voltage output unit, a first switch and a second switch. The voltage regulator receives an operating voltage and a reference voltage generated by a reference voltage generator, and then outputs a corresponding output voltage. The voltage regulator of the present invention can provide an operation mode, a suspend mode and a standby mode and can be switched among these modes to provide corresponding current driving capacity for respective operation states. When in the operation mode, the voltage regulator can supply a great current. When in the suspend mode, the voltage regulator consumes less power. When in the standby mode, the voltage regulator consumes even less power.

  • Patent number: 7772921
    Abstract: A filter and a filtering method are provided. The filter includes a first compare voltage generation unit, a second compare voltage generation unit, a comparator and a first inverter. The first compare voltage generation unit generates a first compare voltage according to an input signal. The second compare voltage generation unit generates a second compare voltage. When the first compare voltage is not over the first reference voltage, the second compare voltage equals the first reference voltage. When the first compare voltage is over the first reference voltage, the second compare voltage equals the second reference voltage. The first reference voltage and the second reference voltage depend on a minimum pulse width. The comparator outputs a filtered signal according to the first compare voltage and the second compare voltage. The first inverter inverts a filtered signal to an output signal.
