Abstract:
An SAR ADC and a conversion method are disclosed, which includes an SAR control logic circuit configured to control A/D conversion by steps: 1) sampling analog input signal for first time; 2) subjecting sampled signal to conversions; 3) sampling analog input signal for another time; 4) subjecting sampled signal in step 3) to conversion comprising: 41) determining whether the lowest M bits of previous N-bit digital output signal are 1's or 0's, if so, looping back to step 2), otherwise, proceeding to step 42); 42) performing conversions on lowest M bits of new N-bit digital output signal, directly taking N-th to (M+1)-th bits of previous N-bit digital output signal as N-th to (M+1)-th bits of new N-bit digital output signal, repeating steps 3) and 4) until analog input signal is fully sampled and converted. Required cycles can be reduced resulting in higher conversion rate and lower power consumption.

Claim (Index 9):
The SAR A/D conversion method of  claim 8 , wherein the sequential steps are performed under a control of a clock signal wherein the sampling in each of steps 1) and 3) lasts for one clock cycle, and wherein the SAR A/D conversion in each of steps 2) and 42) is conducted one clock cycle latter after completion of the corresponding sampling.
