BIPOLAR | NMOS | CMOS |
---|---|---|
Bipolar technology uses BJT for design | NMOS use only field effect transistors for design. | CMOS uses both MOS transistors and PMOS for design |
High power dissipation | Higher power dissipation than CMOS but lower than bipolar. | Low power dissipation |
Low input impedance | High input impedance | |
Medium noise margin | Medium noise margin | High noise margin |
High speed of operation | Medium speed of operation | |
Unidirectional | Unidirectional | Bidirectional |
NMOS propagates only logic 1 that is VDD | CMOS propagates both logic 0 and 1 | |
Non ideal switching device | Ideal switching device |
