Transistor Performance

What is noise margin in a CMOS circuit?

• The difference between the power supply voltage and the threshold voltage of the transistor.

• The maximum voltage difference between the input and output of a CMOS gate that does not cause a change in the logic state.

• The range of input voltage levels over which a CMOS gate correctly recognizes a logic high or low level without error.

• The minimum voltage difference required to ensure that a CMOS gate correctly switches from one logic level to another.

What is power dissipation in an IC?

• The total energy stored in the IC during operation.

• The amount of energy lost as heat in the IC during its operation.

• The power consumed by the IC when it is in standby mode.

• The maximum voltage the IC can handle before it fails.

What is static power dissipation in an integrated circuit (IC)?

• The power consumed by the IC when it is actively switching between logic states.

• The power dissipated due to the charging and discharging of load capacitances in the IC.

• The power consumed by the IC when it is in a steady state, with no switching activity.

• The power lost due to leakage currents in the transistors when the IC is active.

What is dynamic power dissipation in an integrated circuit (IC)?

• The power consumed by the IC when it is in a steady state with no switching activity.

• The power dissipated due to leakage currents in the IC when it is powered off.

• The power consumed by the IC during the charging and discharging of load capacitances as it switches between logic states.

• The power lost due to resistance in the power supply connections of the IC.

What is the effect of propagation delay on the performance of an integrated circuit (IC)?

• It increases the power consumption of the IC.

• It limits the maximum operating speed of the IC.

• It improves the noise margin of the IC.

• It reduces the static power dissipation of the IC.
