Abstract :
Conventional sigma-delta (ΣΔ) analog-to-digital (A/D) converters are based on an analog ΣΔ modulator followed by a digital filter. In this paper we propose a new architecture of a first-order ΣΔ modulator that needs no active analog components. We call this ΣΔ modulator "digital-only," and implement with it A/D converters in FPGA\´s or directly in the software of microprocessors. We here discuss aspects of the dynamic behavior of the proposed structure.
