摘要：

A novel architecture of an asynchronous sigma-delta modulator with noise shaping is introduced. Compared with the conventional solution, the proposed modulator achieves first-order noise shaping without an additional loop filter. With the same sampling frequency, the improvement of the SNDR of the asynchronous sigma-delta modulator can be over 20 dB.
