An ultra high-speed 8-bits analog-to-digital converter design
In this paper, an ultra high-speed 8-bits analog-to-digital converter with digital foreground calibration in 0.18-µm CMOS technology is presented. The spice simulation and the measured results show the folding and interpolating ADC produces 5.9 ENOB with calibration disabled and 7.2 ENOB with calibration Enabled at Nyquist.
