Abstract

We analyze the behavior of a single-loop ΣΔ modulator using a vector quantization (VQ) approach. We extract the encoder-decoder structure typical of VQ, existing in a ΣΔ modulator. The study of the encoding part gives the intrinsic behavior of the modulator. Bounds to the intrinsic performance of the ΣΔ modulator can be derived through this approach in the oversampling situation, assuming periodicity of the bandlimited input signals
