Re: increase lvds speed
The problem is that the output impedance is a model of link and I can't control it. Are there any kind of technique to rise the speed of this lvds?
I've seen a lot of papers for 1-2 Gb LVDS using this kind of schema.
I've enclosed one pictore of ac analisys. As you can...
lvds predriver
I've a problem. When our input is very bad, what can we do? I need some ideas and papers if it's possible.
I've heard something about cml-buffers.
I've read some papers about this.
You can change the two p-mos of the h-bridge for two current sources to have the same current and Vcm with less vdd.
But it's only necessary for vdd<2.5 V
Re: increase lvds speed
referring to the two resistors. I'm reading some papers that said that putting it, you have to doble the current of the system and have better results that with only one. But if it's better for speed purposes, it can be only one.
About the output load of two capacitors...
Re: increase lvds speed
first of all, thanks for the answer. About it, I can't increase my current, It have to be about 3.5 mA to accomplish the standard, doesn't it?
gb lvds
hi,
I'm designing an lvds driver like the figure below. But it have to go in 1Gb and the outup load is killing it.
I've a cutting freq. of 500 MHz aprox. and my output load is two 100 Ohms resistances and two capacitor of 10 pF.
Can you explain me how can I increase its speed?
LVDS design
Hi,
I'm designing an LVDS but I've problems with millers compensation. How can I know the value of Cc and Rc in my system? How can I calculate the poles/zeros of the system.
