  • Reference voltage circuit with low temperature drift
    Patent number: 10831227
    Abstract: Disclosed is a reference voltage circuit with low temperature drift, including a first voltage unit, a second voltage unit and a K times' amplification unit. The first voltage unit is configured to generate a first voltage, with a first end thereof being grounded. The K times' amplification unit is configured to amplify the first voltage by K times, with a first end thereof being connected to a second end of the first voltage unit, and with a second end thereof being connected to a first end of the second voltage unit, wherein K is a constant greater than zero. The second voltage unit is configured to generate a second voltage, with the first end thereof being connected to a current source circuit, and a second end thereof being connected to a third end of the first voltage unit to serve as an output end of a reference voltage (VREF).
