Abstract

Systems, methods, and circuitries are provided to control a gain setting in an analog-to-digital converter (ADC) that converts an analog signal to a digital signal based on a reference voltage. Temperature compensation circuitry includes a temperature gain correction circuitry and a combination circuitry. The temperature gain correction circuitry is configured to determine a correction term based on a temperature that affects the reference voltage. The combination circuitry is configured to combine the correction term with a calibration gain value to generate a corrected calibration gain value and provide the corrected calibration gain value to the ADC to control the gain setting.
