CMOS

  1. 1. Emitter-Coupled Logic Gates Emitter Coupled Logic or ECL is another type of digital logic gate that uses bipolar transistor logic where the transistors are not operated in the saturation region, as they are with the standard TTL digital logic gate.
  2. 2. Enhancement-Type MOSFET • Most widely used field effect transistor (enhancement type) • Let’s look at its structure and physical operation -3 terminal device (gate, source, drain) – Two types: • nMOS and pMOS
  3. 3. Circuit Symbols
  4. 4. MOS gates
  5. 5. A complementary version of the nMOS device is a pMOS shown below Fig. CMOS
  6. 6. PLA
