As already stated, it is necessary for designers to know about the behavior and properties of components and basic circuits and about techniques and particular aspects of implementation. This is why, before going further these elements are grouped together in this part for those who might not be completely familiar with. Analog IC design is a branch of analog design. The difference comes from the integration that has many practical consequences. In turn, these particularities do not allow direct integration of a board schematic and then have an impact on the design:
Analog integrated circuits include both active devices and passive devices connected together in order to achieve their functionality. Integrated components as simple objects are defined by their material, shape and size.
The integrated components will be analyzed in terms of their characteristics and behavior, not in terms of technology except when a direct link exists between process and characteristics.
Integrated components belong to three families:
Availability of particular devices depends on process and options.
These devices are bipolar transistors, MOS transistors and various diodes.
These devices are resistors, capacitors and inductors.
These devices include parasitic capacitors and resistors, isolation diodes, parasitic MOS, parasitic bipolar transistors and parasitic thyristors.
