Sketch the spectrum at the output of a 3-way time-interleaved A/D converter clocked at with . Assume both dc offset and gain mismatches are present, as well as 3rd-order distortion of the input.

A converter with no noise shaping exhibits a SNR of 40 dB over a 1-MHz signal bandwidth. By what factor must the sampling rate be increased (without noise shaping) to obtain a maximum SNR of 80 dB?
