摘要
A pipelined folding-interpolating analog-to-digital converter (ADC) with a distributed quantizer is presented. The mismatch-insensitive analog frontend provides excellent spurious-free dynamic range (SFDR) and signal-to-noise ratio without calibration or digital postprocessing. The algorithm of the digital coder relaxes the requirements on the interface between analog core and digital coder. The single-core ADC achieves an effective resolution of 7.3 b and an SFDR of 52.7 dBc in the second Nyquist band at 6 GS/s with an overall power consumption of 10.2 W.
