    The understanding of noise in analog sampled data systems is vital for the design of high resolution circuitry. In this paper a general description of sampled and held noise is presented. The noise calculations are verified by measurements on an analog delay line implemented using switched current (SI) technique. Based on the knowledge about sampled and held noise a high resolution/low power third order Sigma-Delta modulator is designed in SI technique. The measured performance of the designed Sigma-Delta modulator corresponds well with the expected performance.
