FET Configurations:
FETs (JFETs and MOSFETs) have three configurations just as BJTs have. The three FET Configurations—the common gate, common source, and common drain configuration have been given in Fig. 13.11.
Input and output terminals of different configurations have been given in Table 13.1
TABLE 13.1Â Â FET Configurations
| Configuration | Input Terminal | Output Terminal |
| Common gate | Source | Drain |
| Common source | Gate | Drain |
| Common drain | Gate | Source |
TABLE 13.2Â Â FET-BJT Correspondence
| FET Configuration | BJT Configuration |
| Common gate | Common base |
| Common source | Common emitter |
| Common drain | Common collector |
The three FET configurations have characteristics that are similar to the three corresponding BJT configurations, as given in Table 13.2.
