摘要
In an example, a temperature-corrected voltage reference circuit for use in an integrated circuit (IC) includes a voltage reference circuit, a programmable gain amplifier, and a digital control circuit. The programmable gain amplifier includes a first input coupled to the voltage reference circuit, a second input coupled to receive a control signal, and an output coupled to provide a temperature-corrected voltage reference. The digital control circuit includes an input coupled to receive a temperature signal indicative of temperature of the IC and an output coupled to the second input of the programmable gain amplifier, the digital control circuit generating the control signal in response to the temperature signal.
