| IP개요 | The proposed input-impedance-boosted second-order noise-shaping SAR ADC addresses both energy efficiency and biopotential acquisition requirements. This project aimed to achieve an input impedance comparable to that of a CT-DSM (ContinuousTime Delta-Sigma Modulator) while retaining the advantages of an NS-SAR ADC. This proposed system, implemented using a 0.18-μm CMOS process, maintains a bandwidth of 1 kHz, a power consumption of 15 μW, a figure of merit (FoM) of 178 dB, and an improved input impedance of 100 MΩ. |
