The integration of analogue and digital functions on a single chip is necessary for the development of new information technologies for data communications, industrial applications and consumer products.

The primary objective of ADCIS was the adaptation and characterisation of a 1 micron CMOS process for mixed analogue-digital functions and the extraction of the electrical parameters of a submicron CMOS technology, together with the definition of submicron rules.
The integration of analogue and digital functions on a single chip is necessary for the development of new information technologies for data communications, industrial applications and consumer products.
The primary objective of the project was the adaptation and characterization of a 1 micron complementary metal oxide semiconductor (CMOS) process for mixed analogue digital functions and the extraction of the electrical parameters of a submicron CMOS technology, together with the definition of submicron rules. At the same time, design tools were developed with the goal of building a system capable of being used to produce silicon compilers involving digital and analogue cells. Finally, a complex integrated circuit was designed and manufactured to demonstrate the capabilities of the developed technology and computer aided design (CAD) tools. The most important results achieved by the project were:
developed of 1 micron CMOS analogue modules, integration into an analogue digital process technology, and full characterization;
fabrication of a submicron test circuit and first characterization of the 0.7 micron technology;
mixed analogue/digital building blocks design, fabrication and characterization;
usage and evaluation of the new CAD tools in the design of blocks, test circuits and demonstrator;
design, fabrication and test of a complex integrated circuit (IC) in 1 micron CMOS technology.
