  • FLASH-SAR ADC conversion method and circuit
    Patent number: 12483262
    Abstract: A FLASH-SAR ADC conversion method comprises: at a sampling stage of a FLASH-SAR ADC, sampling an input signal by a SAR ADC module, and at the same time, performing amplification, comparison and high-bit coarse quantization on the input signal by a FLASH ADC module to output a FLASH ADC conversion result, wherein the FLASH ADC conversion result is a temperature code; at a conversion stage of the FLASH-SAR ADC, performing fine quantization on a residual voltage by the SAR ADC module according to the temperature code and the input signal to output a SAR ADC conversion result, and at the same time, sampling a reference voltage or a partial voltage of the reference voltage by FLASH ADC module; and performing encoding on the temperature code and the SAR ADC conversion result to obtain a signal conversion result of the FLASH-SAR ADC.
