The VIL is found from transfer characteristic of inverter by:a)The poi...
The correct answer is option 'B', which states that the VIL is found from the slope of the transition at a point where the slope is equal to -1.
To understand why this answer is correct, let's first understand what VIL represents in the context of an inverter.
What is VIL?
VIL stands for Input Low Voltage. It is the voltage level at the input of an inverter that is considered to be a logical low or '0' state. In other words, any input voltage below VIL is interpreted as a logic low.
Transfer Characteristic of an Inverter
The transfer characteristic of an inverter shows the relationship between the input voltage (Vin) and the output voltage (Vout) of the inverter. It is typically represented by a graph or a plot.
Finding VIL from the Transfer Characteristic
To find VIL from the transfer characteristic of an inverter, we need to look at the slope of the transition at a point where the slope is equal to -1.
Explanation of Option B
Option B states that VIL is found from the slope of the transition at a point where the slope is equal to -1. This means that at this particular point, the change in output voltage (ΔVout) divided by the change in input voltage (ΔVin) is equal to -1.
Significance of Slope -1
When the slope of the transition is equal to -1, it indicates that the inverter is operating in the linear region. In this region, the inverter is neither fully in the high state nor fully in the low state. It is transitioning between the two states. The point where the slope is -1 represents the midpoint of this transition.
The Midpoint of the Transition
The midpoint of the transition is the point where the input voltage is halfway between the input high voltage (VIH) and the input low voltage (VIL). It is the voltage level at which the inverter output switches from a logic high to a logic low, or vice versa.
Conclusion
In conclusion, the VIL is found from the transfer characteristic of an inverter by determining the point at which the slope of the transition is equal to -1. This point represents the midpoint of the transition, where the input voltage is halfway between VIH and VIL.
