The above circuit acts as:
  • a)
    Tristate buffer
  • b)
    NAND gate
  • c)
    Buffer
  • d)
    Inverter
Correct answer is option 'D'. Can you explain this answer?

The above circuit acts as:a)Tristate bufferb)NAND gatec)Bufferd)Invert...
Inverter
  • This is equal to NOT gate in the digital circuitry.
  • The output of this is a compliment of the input.

 
This can be built from the transistors like BJT, MOSFET, etc…
The CMOS inverter consists of the NMOS and the PMOS field-effect transistors connected in one below the other.

 
When In = Low
PMOS will be shorted and output will be High.
When In = High
NMOS will be shorted and output will be Low.
Hence it acts as an inverter.
