    摘要

    Incremental ADCs (IADC) have more advantages and are now popular in high-resolution sensor interface circuits. In this paper, we proposed and demonstrate a power- and area-optimized IADC, using second-order feedforward one-bit modulator. With very simple coefficients scaling, the dynamic range is very wide and it can achieve 90-dB dynamic range and peak SNDR 86.2 dB with 2.6 Vpp, and its occupied area 0.025 mm2. It can achieve 16 kHz bandwidth with power consumption 677 μW, which results in a Schreier FoM 162 dB. It is very suitable for integration on sensor system-on-chip.
