Original Abstract

This paper presents a novel architecture of high-order single-stage sigma-delta (ΣΔ) converter for sensor measurement. The two-step quantization technique was utilized to design of novel architecture of sigma-delta; modulator. The time steps are interleaved to achieve resolution improvement without decreasing of conversion speed. This technique can be useful for low oversampling ratio. The novel architecture was designed to obtain high dynamic range of input signal, high signal-to-noise ratio and high reliability.
