Abstract
A circuit and method for performing a Binary-to-Gray conversion are disclosed. A first binary signal represents a target value and a second binary signal is stored in a register. A set of binary candidate values are determined where the respective Gray equivalent of each binary candidate value has a Hamming distance of one from the Gray equivalent of the second binary value. One of the binary candidate values is selected as a function of the first binary signal and the second binary signal. The selected binary candidate value is provided at input to the register. An encoded signal is generated by determining the Gray encoded equivalent of the selected binary candidate value.
