Abstract
Provided is an ADC circuit based signal digitalization method, including: inputting the analog signal to the ADC circuit, and after being converted by the ADC circuit for the first time, outputting a first ADC output value M; adjusting the least significant bit of the ADC circuit based on the value of the higher bits of the output value M, turning down the least significant bit of the ADC circuit, when all the values of the higher bits of the output value Mare 0; inputting the analog signal to the ADC circuit again, and then outputting the ADC output value Mfor the i+1 time; outputting the final signal conversion result and the adjusted least significant bit based on all the ADC output values. The present invention could improve the ADC precision of small signals without increasing the ADC circuit size.
