    Abstract
    In this work, a switched capacitor-based successive approximation register analog-to-digital converter using a passive reference charge sharing and charge accumulation is proposed. For N -bit resolution, the fully differential version of this architecture needs only 6 capacitors, which is a significant improvement over conventional binary-weighted SAR ADC. The proposed SAR ADC is first modeled in MATLAB, and the effect of practical operational transconductance amplifier limitations such as finite values of gain, unity-gain bandwidth and slew rate on ADC characteristics is verified...
