Abstract: USING SWITCHED CAPACITOR TECHNIQUES, high precision filters can be fully integrated using standard hlOS technology'-3. In determining the usefulness of this approach for a given application, the obvious advantages of small size and low manufacturing cost must be weighed against the disadvantages of the cost and time required to mask-program a desired filter response. This restricts the usefulness of these filters to those applications with sufficient manufacturing volume to justify the expense of the mask pro…
