Abstract

Active filters, realized in thick film circuitry, can offer major advantages over more conventional wiring systems, including the ability to functionally trim them, using a computerized laser trimming system. This paper considers the adjustment methods used for two different active filters and shows how the methods can be extended to filters with more complicated characteristics.
