Abstract :
By incorporating the principle of a closed loop transducer with the over sampled converter the authors obtain a directly digital device having the properties of linear transfer characteristic, frequency response down to DC, self-testing properties and accuracy-to-bandwidth trade off. Prototype transducers have been built and tested
