A 10-bit 100-MS/s two-step ADC was fabricated using a 90 nm CMOS technology. To reduce power dissipation, the ADC uses latch-type comparators for signal digitalization and an open-loop amplifier for residue amplification. The linearity of the residue amplifier is enhanced by digital background...
Again, we can use Equation 3 to find the ADC accuracy and get: Accuracy=3 bits−log2(0.125)=3−(−3)=6 bitsAccuracy=3 bits−log2(0.125)=3−(−3)=6 bits Brief Introduction to Sub-range and Two-step ADCs Let’s examine the above 3-bit ADC fr...

By exploiting the respective advantages of the SAR and TDC architectures, the two-step ADC is realized without a high-gain amplifier for high linearity of a multiplying digital-to-analog converter. Thus, the proposed architecture can implement a low-power ADC without compromising operational speed....
