In this way, the required total capacitance of the ADC is reduced more than 96% compared to a 10-bit conventional SAR (CSAR) ADC. Also, due to noise-shaping property the comparator specifications are relaxed. The ADC is designed and simulated in 90nm CMOS technology with HSPICE simulator. ...
传统模数转换器难以通过单一架构同时满足高精度,低功耗的要求,近年来,一种新型模数转换器混合架构——噪声整形逐次逼近型模数转换器(Noise-shapingSARADC)结合了逐次逼近型模数转换器(SARADC)与Σ-ΔADC架构的优点,能够同时实现高精度,低功耗的性能.然而凭借混合架构的优势,目前Noise-shapingSARADC的设计一般也难以实现...
The noise-shaping successive approximation register (NS-SAR) ADC is an emerging hybrid architecture that achieves high resolution and power efficiency simultaneously by combining the merits of the SAR ADC and the ΔΣ ADC. They have the merits of simple, highly digital, and low-voltage tolerant,...
Although charge-redistribution successive approximation (SAR) ADCs are highly efficient, comparator noise and other effects limit the most efficient operation to below 10-b ENOB. This work introduces an oversampling, noise-shaping SAR ADC architecture that achieves 10-b ENOB with an 8-b SAR DAC ...
