Abstract:

Noise-Shaping (NS) SAR ADCs can have high Dynamic Range (DR) and be easily adopted to IoT, audio and many other applications. This paper proposes four techniques to improve the DR and conversion speed of NS SAR ADCs. A prototype NS SAR ADC achieves SNDR/SNR/SFDR of 98.3dB/99.3dB/108.5dB with 100kHz bandwidth and 12.8MS/s. Schreier FoM reaches 175.3dB.
