VLSI-1A

What is the expansion of VLSI

• Very Long Scale Integration

• Very Long Scale IC

• Very Large Scale Integration

• Very Large Scale ic

Expansion of MOS is

• Metal Oxide Silicon

• Metal Oxide Semiconductor

• Metal Oxide Silicondiode

• Metal oxide Signboard

In NMOS transistor, when voltage applied to gate is '1' logic , the transistor acts like

• open switch

• closed switch

• gets burnt

• nothing happens

The logic gate whose output is '1' when one of the inputs is '1' is called

• AND gate

• OR gate

• XOR gate

• XNOR gate

The logic gate in which output ='1' when both inputs are different is called

• AND gate

• OR gate

• XOR gate

• XNOR gate

In this circuit, when inputs a=0, b=1, what is the output 

• 1

• 0

• High impedance 

• Shortcircuit

NAND gate is the complement of AND gate

• True

• False

In PMOS transistor , when gate voltage ='0' logic, the transisor

• conducts

• does not conduct

• acts like open switch

• burns

PMOS transistor is used to pass

• 0

• 1

• infinity

• any information

 $f=\ \overline{x.y}$    This function represents

• AND gate

• NAND gate

• OR gate

• NOR gate
