  • Abstract
    This paper presents the first implementation results for a time-interleaved continuous-time ΔΣ modulator. The 3rd-order low-pass modulator operates at an oversampling ratio of 5 with a time-interleaving factor of 2 at sampling frequencies of 100MHz and 200MHz. It achieves an SNDR of 57dB and 49dB in signal bandwidths of 10MHz and 20MHz, respectively.
