13. Identify the NMOS gate circuit shown.

  1. AND gate
  2. OR gate
  3. NOT gate
  4. NAND gate
  5. NOR gate

2 is CORRECT. This is a five transistor logic circuit; the leftmost three form a NOR gate, while the rightmost two form an inverter. Pictures of these are given in the picture file. The combination of the NOR and inverter is a OR gate.
