An 11-b 160-MS/s 4-channel time-interleaved double-sampled pipelined ADC implemented in a 0.35-µm CMOS process is describe. Digital calibration is used to correct mismatch errors between channels as well as the memory errors that arise from the use of double sampling. The signal-to-noise-and-distortion ratio is improved from 45 dB to 62 dB after calibration with a 8.7 MHz input. The spurious-free-dynamic-range is increased from 47 dB to 78 dB.
