  • Bandgap reference circuit for reducing power consumption and method of using the same
    Patent number: 10671108
    Abstract: A bandgap reference circuit and method of using the same are provided. The bandgap reference circuit includes a startup component; an output component; and a bandgap core component coupled there-between. The bandgap core component includes a reference point having a voltage associated with an output signal of the output component. A controller is configured for controlling the bandgap core component and the output component to switch between a low power consumption mode and a normal operation mode based on the voltage at the reference point. When the bandgap core component and the output component operate in the normal operation mode, the bandgap reference circuit outputs a stable voltage and has a first power consumption. When the bandgap core component and the output component operate in the low power consumption mode, the bandgap reference circuit has a second power consumption less than the first power consumption.

  • Level-shifter circuits and methods of using the same
    Patent number: 10469086
    Abstract: Level-shifter circuits and methods of using the same are provided. A level-shifter circuit includes a latch unit and a level-shifting unit. The latch unit is configured to generate a latch signal for storing a logic state of a first digital signal in a first power supply domain. The level-shifting unit is configured to shift a voltage of the latch signal to output a second digital signal in a second power supply domain. The latch unit and the level-shifting unit are powered by a power supply voltage in the second power supply domain.
