The delta-sigma ADC includes a plurality of integrator stages connected in series, including a first integrator stage operatively coupled to an input of the delta-sigma ADC; a main quantizer circuit including a main ADC circuit and a main digital-to-analog converter (DAC) circuit, wherein an input to the main ADC circuit is operatively coupled to the plurality of integrator stages; and a first feedback circuit path operatively coupled from an output of the first integrator stage to the input of the delta-sigma ADC, wherein the first feedback circuit path is configured to subtract an output voltage of the first integrator stage from the input of the delta-sigma ADC. The baseband circuitry is configured to activate the first feedback circuit path when detecting that the input voltage increases to cause distortion in the delta-sigma ADC."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus to increase dynamic range in delta-sigma ADC using internal feedback across all integrators in loop-filter","description":"An apparatus comprises a delta-sigma analog-to-digital converter (ADC) and baseband processing circuitry.
