Abstract
Some embodiments include an encoder to convert a thermometer code into a binary code output information or a Gray code output information. The encoder supports blind input swapping, such that it provides correct output information without prior knowledge of the input swapping. Some embodiments also include a truth table that has additional rows to describe output information when input information at inputs of the encoder is swapped. The encoder includes symmetrical logic functions with respect to information at its inputs as building blocks.
