Abstract
A 1.8V folding-interpolating ADC in 0.18/spl mu/m CMOS uses small device sizes to achieve a conversion rate exceeding 1.6GS/s. The inherent mismatch offsets are calibrated transparently, and at 1.6GS/s the ADC achieves 0.15LSB DNL, 0.35LSB INL, 7.5 ENOB at 100MHz input, and 7.26 ENOB at Nyquist.
