1.A two-way time interleaved data converter is clocked to achieve anaggregate sampling rate of 500 MS/s.A 181-MHz input sinusoidal signalis applied,and the output spectrum up to the Nyquist frequency of 250MHz is shown in Figure 2 below.Considering offset and gain mismatches,as well as nonlinearities as expected in a fully-differential design,identifythe source of each tone in the spectrum.043 MHz69 MHz181 MHz250 MHzFigure 2
