Abstract
We describe a novel single amplifier loop filter circuit realized with an op amp and RC elements for the oversampling A/D converter. By computer simulation and the experimental evaluation of a trial circuit realized with discrete elements, we confirm that the proposed A/D converter works practically. Furthermore, we evaluate the influence of the op amp´s finite gain responses on the noise transfer function
