A system implementing the techniques according to an embodiment includes a calibration signal generator configured to generate a calibration tone, located in a first frequency band, in response to a calibration enable signal. The system also includes a signal summing circuit configured to generate an ADC input signal as a sum of a received signal and the calibration tone. The received signal is located in a second frequency band. The system further includes an ADC circuit configured to convert the ADC input signal to a baseband digital output signal and to perform self-calibration, based on the calibration tone, in response to the calibration enable signal. The frequency bands and the amplitude of the calibration tone are chosen to reduce interference between the received signal and the calibration tone."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Calibration signal generation for a sampling analog to digital converter","description":"Techniques are provided for the generation of a calibration signal for use on an analog to digital converter (ADC).
