Jitter problem in switching converter

[bicave]

In switching converter we often met jitter, which things make jitter? do you have any paper or material regarding this.

Thanks

Jitter problem

many stuff make jitter
in A/D clock generation unit contribute the apture error, use dll to alleviate.

It is usually caused by noise. You must optimize noise in your circuit. Some sensitive circuits like EA must be carefully isolated from switching noise.

Re: Jitter problem

Phase noise and jitter are different ways of quantifying the same phenomenon. In the ideal world, the duration of a perfectly pulsed signal at a certain frequency level – 1 MHz, for instance – would be exactly 1 μs, with an alternating edge every 500 ns. Such a signal, unfortunately, does not exist. As shown in Figure 1, there are bound to be variations in the length of the period, which causes uncertainty about when the next edge of the signal will occur. This uncertainty is phase noise or jitter.

Re: Jitter problem

In brief jitter can be considered as the noise in the time domain,and lots of non idea conditions such as noisy power supply,clcok feefthrough,substrate coupling...

For better understanding you can refer to some application notes form ADI,Angilent,Tektronix,TI...

One of the reasonsfor jitter is the bandwidth of the device is not enough to support the signal speed.

jitter is time domain of phase noise
