A User´s Approach to the Design of Custom Monolithic Integrated Circuits

This paper describes a design technique which may be taken by a potential user of linear integrated circuits who wishes, for technical and proprietary reasons, to develop custom silicon monolithic integrated circuits. Essentially this approach provides a set of IC´components interconnected to furnish building blocks which contain the singular active and passive device characteristics available in monolithic integrated circuits. The steps are detailed by which the integrated circuit device requirements, monolithic processing sequence and device geometries were established. The performance characteristics of the resultant IC components are also described. Finally, circuit examples are shown which illustrate how the use of these building blocks is necessary for an optimum linear integrated circuit design.
