Applicability of the General Expression
For prediction purposes, microelectronic devices can be divided into four main categories:
• Digital - Small and Medium Scale Integration (SSI/MSI).
• Digital - Large Scale Integration (LSI).
• Memories.
• Linear devices.
The general expression given at equation (3.1) can be applied to all the above categories except linear devices. For linear devices, the active pin factor is in effect unity (due to the low number of pins involved), and the model is thus:
