2.1. BJT and MOSFET Schematic Symbols, Terminal Voltages, and Branch Currents

The BJT can be either a pnp or an npn. The MOSFET similarly can be a pmos or an nmos. The equivalents are npn and nmos and pnp and pmos. The following discussion is based on the npn and nmos, as shown in Fig. 2.1. (All polarities and current directions are reversed for the pnp and pmos. This provides for important versatility in applications.)

Figure 2.1. BJT npn and MOSFET nmos transistors. The terminal configurations are designated common emitter and common source.

The BJT terminals are designated collector, base, and emitter while those of the MOSFET are drain ...
