Integrated circuits for converting analog signals to digital signals, systems, and operating methods thereof

摘要

An integrated circuit that is capable of converting an analog signal to at least one digital signal is provided. The integrated circuit includes a first input end capable of receiving a first analog signal. A first set of 2n-1 inverters are capable of quantizing the first analog signal and outputting a first set of 2n-1 digital values. Each of the first set of 2n-1 digital values is either 0 or 1. A first adder is coupled with the first set of 2n-1 inverters. The first adder is capable of summing the first set of 2n-1 digital values, outputting a first integer value that is capable of corresponding to at least one digital signal.
