EC8095_VLSI Design_IAT1_Part A

The number of transistors in a chip gets doubled for every 18 months is called ________________<br />

• Newtons law
• Moores law
• square law
• Lenz law

Transistors are used to ________________

• Amplification/increasing strength of signal
• degrading the signal
• to pass the signal<br />
• none of these

In CMOS, the pull up network and pull down network consists of ________________ and ________________respectively.

• PMOS & NMOS
• NMOS & PMOS
• ONLY PMOS
• ONLY NMOS

iIn CMOS inverter, when Vin = 0, the direct path exists between ________________ and ________________

• VDD to VSS
• VDD to Output
• output to VSS
• none of these

When a direct path exists between VDD to VSS then it leads to ________________power consumption.

• static
• dynamic
• no power
• none of these

For 2 input NAND gate, the two nmos transistors are connected in ________________in pull down network

• parallel
• straight line
• series
• any form

MOSFET is also called as________________

• FinFET
• CNTFET
• SET
• IGFET

In stick diagram, to represent p-diffusion and n-diffusion, the colours ________________ and ________________ are used respectively.

• red & green
• yellow and green
• blue and green
• red and yellow

When an nmos and pmos is used alone as an imperfect switch, then it is called as ________________

• Transmission gate
• cmos inverter
• Pass transistor
• all the above

Both the control inputs and its complementary are required by the transmission gate, this is called ________________

• Double rail logic
• cmos logic
• single rail logic
• none of the above
