## What is the hold required time in NS?

Hold time is typically defined as a minimum time. An example is that a hold time of 2 ns (min) implies that the data must be stable at least 2 ns after the latching clock edge. The keep out window is defined as the total window around the latching clock edge which includes both the set-up and hold times.

## What is the clock period of a clock frequency of 1 GHz?

Clock Time

It is the reciprocal of the clock frequency. For example, a 1 GHz processor has a cycle time of 1.0 ns and a 4 GHz processor has a cycle time of 0.25 ns. Clock time is affected by circuit technology and the complexity of the work done in a single clock.

## What is clock cycle?

In computers, the clock cycle is the amount of time between two pulses of an oscillator. … The clock cycle helps in determining the speed of the CPU, as it is considered the basic unit of measuring how fast an instruction can be executed by the computer processor. A clock cycle is also known as a clock tick.

## What is maximum clock frequency?

Maximum Clock Frequency is a highest frequency at which the clock input of a IC can be drive, while maintaining proper operation. It is denoted by fmax.

## What is a clock frequency?

In computing, the clock rate or clock speed typically refers to the frequency at which the clock generator of a processor can generate pulses, which are used to synchronize the operations of its components, and is used as an indicator of the processor’s speed.

## What is the maximum clock frequency that I can apply to this FF?

Maximum operating frequency f , of the Toggle Flip-Flop (static frequency divider) as a function of the circuit’s main bias. The absolute maximum corresponds to f = 393 GHz, whereas the widest margins of operation correspond to 325 GHz input frequency.

## What is the minimum clock period for D flip flop?

The minimum clock period is 1.5+3+1.5+0.5=6.5 ns. 2. There are no hold time violations because the minimum flip flop propagation delay is larger than the hold time plus the skew. The maximum delay for the next state logic is 5 ns.
