NONLINEARITY CORRECTION TECHNIQUES FOR HIGH-SPEED, HIGH-RESOLUTION A D CONVERSION/

In general, low resolution circuitry can be designed with higher speed performance than high resolution circuitry, Most high resolution A/D converter architectures require a high resolution component, such as a S/H or integrator, in their design and are often limited by the speed of this component, This paper discusses several techniques for achiev ing high resolution A/D conversion by calibrating nonlinear circuitry with highly accurate reference circuitry without conversion speed bein g limited by the calibration circuitry, The analysis of a sample conve rter with various nonidealities is presented, along with supporting si mulation results for a similar architecture,
