Patent ID: 8362937

Claim:
An integrated circuit being capable of converting an analog signal to at least one digital signal, the integrated circuit comprising: a first input end capable of receiving a first single analog signal; a first set of 2 n -1 inverters directly connected to the first input end, the first set of 2 n -1 inverters each receiving the first single analog signal and being capable of quantizing the first single analog signal and outputting a first set of 2 n -1 digital values, each of the first set of 2 n -1 digital values being either 0 or 1 and n≧2; and a first adder coupled with the first set of 2 n -1 inverters, the first adder being capable of summing the first set of 2 n -1 digital values, outputting a first integer value that is capable of corresponding to at least one digital signal.
