  • Abstract
    An 8-channel 6-bit 16-GS/s time-interleaved ADC was fabricated using a 65nm CMOS technology. Each A/D channel is a flash ADC using latch-type comparator with background offset calibration. Timing skews among the channels are also continuously calibrated in the background. The chip achieves 42.3dB SFDR and 30.8dB SNDR at 16 GS/s sampling rate.
