    What is the function of an inverter in digital circuits?

    Performs a Boolean operation on a single input variable.

    What does the inverter threshold voltage (Vth) indicate?

    The point where the output switches from high to low.

    How does the output voltage behave when the input voltage is between 0 and Vh?

    The output voltage remains at VDD, interpreted as logic '1'.

    What is the significance of the voltage transfer characteristic (VTC)?

    Describes the relationship between input and output voltages under DC conditions.

    What are the critical voltage points that characterize the inverter's behavior?

    VOL, VOH, VIL, VIH, and Vth.

    What happens if the input voltage exceeds VIH?

    The inverter interprets the input as logic '1'.

    What is the maximum allowable input voltage interpreted as logic '0'?

    VIL.

    What is the minimum allowable input voltage interpreted as logic '1'?

    VIH.

    How does noise affect the reliability of inverter circuits?

    It can cause incorrect interpretation of input signals.

    What is the formula for calculating DC power dissipation in an inverter?

    PDC = VDD * IDC.

    What is the trade-off in inverter design regarding chip area?

    Minimizing transistor area may conflict with noise margins and output capability.

    What is the role of the load device in an nMOS inverter?

    It affects the characteristics and performance of the inverter circuit.

    What is the uncertain region in the context of inverter input voltages?

    The voltage range between VIL and VIH where inputs may not be processed correctly.

    What is the effect of reducing the width of the uncertain region?

    It increases noise margins and improves circuit reliability.

    What is the relationship between the input voltage and output voltage in an ideal inverter?

    The output switches sharply between high and low states.
