  • Abstract
    A Hybrid CLS-opamp/ZCBC pipelined ADC is introduced to improve accuracy, robustness, and power efficiency. Fast and accurate residue amplification is achieved by invoking a short ZCBC operation followed by CLS-opamp settling. Measured ENOB is better than 11 b at sampling rate of 20 MHz.
