The history of the application of semiconductors for controlling
currents goes back all the way to 1926, in which Julius Lilienfeld
led a patent for a "Method and apparatus for controlling electric
currents" [1], which is considered the rst work on
metal/semiconductor eld-effect transistors. More well-known is the
work of William Shockley, John Bardeen and Walter Brattain in the
1940s [2, 3], after which the development of semiconductor devices
commenced. In 1958, independent work from Jack Kilby and Robert
Noyce ledto the invention of integrated circuits. A few milestones
in IC design are the rst monolithic operational ampli er in 1963
(Fairchild?A702, Bob Widlar) and the rst o- chip 4-bit
microprocessor in 1971 (Intel 4004). Ever since the start of the
semiconductor history, integration plays an imp- tant role:
starting from single devices, ICs with basic functions were
developed (e. g. opamps, logic gates), followed by ICs that
integrate larger parts of a s- tem (e. g. microprocessors, radio
tuners, audio ampli ers). Following this trend of system
integration, this eventually leads to the integration of analog and
d- ital components in one chip, resulting in mixed-signal ICs:
digital components are required because signal processing is
preferably done in the digital - main; analog components are
required because physical signals are analog by nature.
Mixed-signal ICs are already widespread in many applications (e. g.
- dio, video); for the future, it is expected that this trend will
continue, leading to a larger scale of integration.
