Embodiment Construction
[0019] The traditional charge redistribution N-bit SARADC consists of a binary capacitor array, assuming that the expression of each capacitor is as follows:
[0020] C i = 2 i-1 C 0 +δ i (i∈1,2,…N)(1)
[0021] where C i Indicates the i-th capacitance value of the binary capacitor array, δ i Indicates the error corresponding to the i-th capacitor, and the variance of the error is:
[0022] E [ δ 1 2 ] = σ 0 2 C 0 2 - - - ( 2 )
[0023] E [ δ i 2 ] = 2 i - 1 σ 0 2 C ...
