Hold Time at Low logic Solution

Follow our step by step solution on how to calculate Hold Time at Low logic?

FIRST Step Consider the formula

T hold0 = t ar - T setup1

Next Step Substitute values of Variables

∴

T hold0 = 14ns - 5ns

Next Step Convert Units

∴

T hold0 = 1.4E-8s - 5E-9s

Next Step Prepare to Evaluate

∴

T hold0 = 1.4E-8 - 5E-9

Next Step Evaluate

∴

T hold0 = 9E-09s

LAST Step Convert to Output's Unit

∴

T hold0 = 9ns

Formulas to find Setup Time at High Logic

Other formulas in CMOS Time Characteristics category

Go Aperture Time for Rising Input

t ar = T setup1 + T hold0

Go Aperture Time for Falling Input

t af = T setup0 + T hold1

Go Setup Time at High Logic

T setup1 = t ar - T hold0

Go Setup Time at Low Logic

T setup0 = t af - T hold1

How to Evaluate Hold Time at Low logic?

Hold Time at Low logic evaluator uses Hold Time at Low Logic = Aperture Time for Rising Input-Setup Time at High Logic to evaluate the Hold Time at Low Logic, The Hold Time at Low logic is the minimum time after a clock edge during which a data input signal must remain stable at a low voltage level (binary '0') in a digital circuit. This timing requirement ensures proper data capture and prevents errors in the receiving circuit. Hold Time at Low Logic is denoted by T_hold0 symbol.

How to evaluate Hold Time at Low logic using this online evaluator? To use this online evaluator for Hold Time at Low logic, enter Aperture Time for Rising Input (t_ar) & Setup Time at High Logic (T_setup1) and hit the calculate button.

FAQs on Hold Time at Low logic

What is the formula to find Hold Time at Low logic?

The formula of Hold Time at Low logic is expressed as Hold Time at Low Logic = Aperture Time for Rising Input-Setup Time at High Logic. Here is an example- 9E+9 = 1.4E-08-5E-09.

How to calculate Hold Time at Low logic?

With Aperture Time for Rising Input (t_ar) & Setup Time at High Logic (T_setup1) we can find Hold Time at Low logic using the formula - Hold Time at Low Logic = Aperture Time for Rising Input-Setup Time at High Logic.

Can the Hold Time at Low logic be negative?

No, the Hold Time at Low logic, measured in Time cannot be negative.

Which unit is used to measure Hold Time at Low logic?

Hold Time at Low logic is usually measured using the Nanosecond[ns] for Time. Second[ns], Millisecond[ns], Microsecond[ns] are the few other units in which Hold Time at Low logic can be measured.
