Abstract
A method of converting a thermometer code in an analog-to-digital converter to a binary code. The method involves counting the ones in the thermometer code and using the parity of the count as bit of the binary code; downsampling the thermometer code by dropping every other bit to form a downsampled code; counting the ones in the downsampled code, and using the parity of that count as bit of the binary code; and repeating the procedure until the binary code is completed. A circuit carrying out this method in a single clock cycle without computations is disclosed.
