Analog to digital converter e.g. pipeline converter, has concatenation device to concatenate total weighted correction value and doubled digital output value to provide corrected output value, and condenser unit have unit condensers

摘要

The converter has converter stages, each with a correcting unit including a memory to store weighted correction values for each condenser unit of the stage. Another memory of the correcting unit stores a total weighted correction value for each digital converter output value. A shifting unit multiplies the digital value to obtain an ideal weighted digital converter output value. A concatenation device (4) concatenates the total weighted correction value and the doubled digital output value to provide a corrected output value. The condenser units have a preset number of unit condensers.
