Setup time is the minimum amount of time the data input should be held steady before the clock event, so that the data is reliably sampled by the clock. Hold time is the minimum amount of time the data input should be held steady after the clock event, so that the data is reliably sampled by the clock. Aperture is the sum of setup and hold time ...
Here, the contamination delay is the amount of time needed for a change in the flip-flop clock input to result in the initial change at the flip-flop output (Q). If there is insufficient delay from the output of the first flip-flop to the input of the second, the input may change before the hold time has passed. Because the second flip-flop is ...
Hold time may refer to: In digital electronics, the minimum amount of time the data input should be held steady after the clock event for reliable sampling; see Flip-flop (electronics)#Timing considerations; The amount of time spent in a phone queue on hold (telephone) Hold Time, by M. Ward
In electronics, a sample and hold (also known as sample and follow) circuit is an analog device that samples (captures, takes) the voltage of a continuously varying analog signal and holds (locks, freezes) its value at a constant level for a specified minimum period of time. Sample and hold circuits and related peak detectors are the elementary ...
A timing diagram can contain many rows, usually one of them being the clock. It is a tool commonly used in digital electronics, hardware debugging, and digital communications. Besides providing an overall description of the timing relationships, the digital timing diagram can help find and diagnose digital logic hazards .
There are two types of violation that can be caused by clock skew. One problem is caused when the clock reaches the first register and the clock signal towards the second register travels slower than output of the first register into the second register - the output of the first register reaches the second register input faster and therefore is clocked replacing the initial data on the second ...
The concept of shorting stocks is often misunderstood by retail investors like you and me. Shorting can be demonized by companies, politicians, and commentators when it contributes to bringing a ...
A simple example of metastability can be found in an SR NOR latch, when both Set and Reset inputs are true (R=1 and S=1) and then both transition to false (R=0 and S=0) at about the same time. Both outputs Q and Q are initially held at 0 by the simultaneous Set and Reset inputs.
