An 84dB-SNDR Low-OSR 4th-Order Noise-Shaping SAR with an FIA-Assisted EF-CRFF Structure and Noise-Mitigated Push-Pull Buffer-in-Loop Technique

With the combined merits of the SAR and the ΔΣ ADCs, the noise-shaping (NS) SAR architecture can achieve high resolution with a mild OSR, making it versatile for a wide range of applications. Nonetheless, designing a highly power-efficient NS-SAR …
