  • Systems and methods for initializing bandgap circuits
    Patent number: 11829177
    Abstract: A semiconductor device may include a bandgap circuit that outputs a reference voltage. The bandgap circuit may include a bandgap core circuit and a startup circuit coupled to the bandgap core circuit. The startup circuit may connect a voltage source to a node that corresponds to an output of the bandgap core circuit in response to the bandgap core circuit being initialized. The startup circuit may also disconnect the voltage source from the node in response to the output voltage being equal to or greater than a desired voltage (e.g., a threshold voltage) and one or more local voltages of the bandgap core circuit being equal to or greater than a local threshold voltage.
