Modeling of 4th-order single-bit single-loop Sigma-Delta (Σ-Δ) Modulator for Sensor Applications

In this paper, Modeling of sigma-delta (Σ-Δ) modulator is presented for high resolution sensor applications. This modeling is simulated on a fourth-order single-loop single-bit architecture with an oversampling ratio of 125 and a sampling frequency of 1㎒ for 4㎑ baseband.
