摘要：

This paper proposes a new delay cell for noise-coupled delta-sigma analog-to-digital converters, which simplifies the design of noise-coupling circuits, as well as of the clock generator. Next, a second-order noise-shaping enhancement technique is introduced, and its architecture and circuit implementation discussed. To verify the proposed design methodology, a noise-coupled ADC was designed and simulated.
