摘要：

This paper introduces a new architecture for sensor interface circuits using a delta-sigma modulator. The three-level force feedback allows the use of a digital compensator to stabilize the loop. A 3rd-order delta-sigma structure shapes the op-amp noise and allows a two-chip implementation with high loop gain at low frequencies.
