  • 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.

  • Patent number: 10607662
    Abstract: A Static Random Access Memory (SRAM) array power supply circuit is presented. The circuit comprises an SRAM test unit having a substantially same structure as a basic SRAM unit in the SRAM array; a switch device connected to a power source, the SRAM test unit, and the SRAM array; and a switch control circuit connected to the SRAM test unit and the switch device. When a test voltage in the SRAM test unit is lower than a threshold voltage, the switch device is closed so that the power source begins to charge the SRAM array and the SRAM test unit. The SRAM test unit provides an early warning for the SRAM array, allowing the latter to be charged upon fulfillment of a condition (e.g., charge is low). Compared to conventional circuits, this circuit provides an output voltage that is more stable and less susceptible to the changes in external conditions such as temperature or pressure.
