Features of ICs
- An IC perform complex functions. Example: a single transistor cannot amplify signal voltage, whereas an IC perform function of amplification.
- Reliability and cost are not affected by an increase in complexity of ICs.
- In an IC, the adjacent components are spaced mostly 50-100 micrometer apart.
- In an IC, interconnection of individual elements is made through metallization (i.e. without soldering and welding)
Characteristics of Digital ICs
Digital circuits are constructed by using different logic gates, so when we use different ICs, we have to produce different logic gates using different technologies. For the fabrication of ICs, we use semiconductor devices-bipolar and unipolar. Based on the devices, digital ICs are made which are then commercially available. When we use a bipolar device, like a transistor in the IC fabrication technology, it is known as bipolar technology. In unipolar technology, we make use of unipolar devices. e.g., MOSFETs. A group of compatible ICs with the same logic level and supply voltages for performing various logic functions which have been fabricated using specified configuration, is referred to as a logic family.
