  • Ratiometric current or voltage source circuit with reduced temperature dependence
    Patent number: 11831314
    Abstract: A ratiometric current source circuit having a reduced temperature dependence is disclosed. An embodiment of the current source circuit includes a first divider circuit configured to generate a reference voltage using a voltage level of a power supply node and a second divider circuit including a first resistor with a first temperature coefficient and a second resistor with a second temperature coefficient. The first resistor is configured to generate a first current using an input voltage and the voltage level of the power supply node and the second resistor is configured to generate a second current using the input voltage. The embodiment further includes a buffer circuit configured to generate the input voltage using the reference voltage and generate an output current using a difference between the first current and the second current.
