Edge Rate Solution

STEP 0: Pre-Calculation Summary

Formula Used

Edge Rate = (Rise Time+Fall Time)/2
t_e = (t_r+t_f)/2
This formula uses 3 Variables

Variables Used

Edge Rate - (Measured in Second) - Edge rate is defined as the ratio of rise time to the fall time.
Rise Time - (Measured in Second) - Rise Time is defined as the time required for a pulse to rise from 10 per cent to 90 per cent of its steady value in CMOS devices.
Fall Time - (Measured in Second) - Fall time is time for a waveform to fall from 80% to 20% of its steady-state value.

STEP 1: Convert Input(s) to Base Unit

Rise Time: 2.8 Nanosecond --> 2.8E-09 Second (Check conversion here)
Fall Time: 9.2 Nanosecond --> 9.2E-09 Second (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

t_e = (t_r+t_f)/2 --> (2.8E-09+9.2E-09)/2

Evaluating ... ...

t_e = 6E-09

STEP 3: Convert Result to Output's Unit

6E-09 Second -->6 Nanosecond (Check conversion here)

FINAL ANSWER

6 Nanosecond <-- Edge Rate

(Calculation completed in 00.004 seconds)

Explain Sizing Of The Inverter?

Sizing of an inverter in digital circuit design refers to determining the appropriate dimensions (width and length) of the transistors within the inverter circuit. An inverter is a fundamental building block in digital circuits, and its sizing plays a crucial role in determining various aspects of the circuit's performance, including speed, power consumption, and noise margins.

How to Calculate Edge Rate?

Edge Rate calculator uses Edge Rate = (Rise Time+Fall Time)/2 to calculate the Edge Rate, The Edge rate formula refers to the rate of change of voltage or current at the transition point of a digital signal. It is a measure of how quickly a signal changes from one logic level to another. In other words, edge rate quantifies the steepness or slope of the transition in a digital signal. Edge Rate is denoted by t_e symbol.

How to calculate Edge Rate using this online calculator? To use this online calculator for Edge Rate, enter Rise Time (t_r) & Fall Time (t_f) and hit the calculate button. Here is how the Edge Rate calculation can be explained with given input values -> 4.7E+9 = (2.8E-09+9.2E-09)/2.

FAQ

What is Edge Rate?

The Edge rate formula refers to the rate of change of voltage or current at the transition point of a digital signal. It is a measure of how quickly a signal changes from one logic level to another. In other words, edge rate quantifies the steepness or slope of the transition in a digital signal and is represented as t_e = (t_r+t_f)/2 or Edge Rate = (Rise Time+Fall Time)/2. Rise Time is defined as the time required for a pulse to rise from 10 per cent to 90 per cent of its steady value in CMOS devices & Fall time is time for a waveform to fall from 80% to 20% of its steady-state value.

How to calculate Edge Rate?

The Edge rate formula refers to the rate of change of voltage or current at the transition point of a digital signal. It is a measure of how quickly a signal changes from one logic level to another. In other words, edge rate quantifies the steepness or slope of the transition in a digital signal is calculated using Edge Rate = (Rise Time+Fall Time)/2. To calculate Edge Rate, you need Rise Time (t_r) & Fall Time (t_f). With our tool, you need to enter the respective value for Rise Time & Fall Time and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
