Abstract: A thermometer coded line is configured to convert a time interval to a digital code for subsequent processing in order to output a value representative of said time interval. A digital peak detector is coupled to receive output from the thermometer coded line, the detector operating for correction of an undesired code of said digital code in order to ensure a valid output of said value. A majority logic circuit is coupled between the thermometer coded line and the digital peak detector, the logic circuit operating for correction of undesired code of said digital code in order to ensure the valid output of said value. The detector functions to correct any undesired code not corrected by, or introduced by, the logic circuit.
