Abstract:
1. An analog-to-digital converter for converting an analog input signal into a digital binary output signal, comprising: a reference unit for generating a measuring signal based on a comparison of the input signal with a reference voltage, a first logic circuit connected to the reference unit for generating an intermediate signal based on the measuring signal, and a second logic circuit connected to the first logic circuit for generating the digital binary output signal based on the intermediate signal, wherein the measuring signal comprises a bit word from a first set of bit words and the intermediate signal comprises a bit word from a second set of bit words, each bit word representing a unique value, and two bit words from the second set which belong to two consecutive unique values, respectively, differ by no more than one bit, and wherein the bit words from the second set are arranged in rows in a matrix in which the order of the rows corresponds to the unique values represented by the bit words, while in operation each bit of the bit word of the measuring signal is applied to only one input port of the first logic circuit, and wherein the respective numbers of bit changes in the respective columns of the matrix formed by the bit words of the second set are substantially equal.
