| 摘要 | In this paper, a low-voltage passive first-order noise shaping charge-redistribution successive approximation register (SAR) ADC with energy-efficient switching method is proposed. The energy -efficient switching method is achieved by one-side switching instead (OSSI) method and higher-bit switching instead (HBSI) method. The architecture is modified to realize the noise- shaping loop properly. We present a passive integrator with a dynamic DC offset to address the path gain error from the varying voltage on the capacitor array at each quantization step. Simulation results on a 180nm CMOS technology operated at 0.6V supply and 25kHz sampling rate show 130n W power consumption with a peak SNDR of 70.3dB.. © 2023 IEEE. |
