摘要

描述了一种用于宽带低功耗δ - σ adc的直接电荷转移加法器。详细论述了其工作原理和设计。并介绍了其在噪声耦合δ - σ adc中的应用。为了验证所提出的设计方法，设计并仿真了一个使用直接电荷转移加法器的二阶噪声耦合delta-sigma ADC。

Wideband ΔΣ ADCs using direct-charge-transfer adder

A direct-charge-transfer adder is described for wideband low-power delta-sigma ADCs. Its operation and design are discussed in detail. Its application to noise-coupled delta-sigma ADCs is also described. To verify the proposed design methodology, a 2nd order noise-coupled delta-sigma ADC using direct-charge-transfer adder has been designed and simulated.
