  • Bandgap reference circuit for producing fixed reference signals
    Patent number: 12669836
    Abstract: Embodiments disclosed herein relate to reference signals produced by integrated circuits. In an example, a reference circuit is provided. The reference circuit includes a first transistor, a second transistor, and an operational amplifier. The first transistor includes an input configured to couple to a voltage supply, an output coupled to a first resistor and a second resistor, and a control coupled to an output of the operational amplifier. The first resistor is coupled in series with a third resistor, and the second resistor is coupled in series with the second transistor. The second transistor includes an input and a control coupled with the second resistor and an output coupled to ground. The operational amplifier includes a first input coupled between the first and third resistors and a second input coupled between the second resistor and second transistor.
