Hi,
I am designing a 10 Gbps laser driver using commercially available ICs. At the moment, I noticed that there is significant noise in the resulting eye diagram. This noise is reduced when I touch the circuit (to be precise, the interface line between the IC and the laser) with my bare hands - pictures attached
hence, can someone help me with these questions?
What's the effect of touching a circuit using our bare hands?
How does this reduce high frequency noise?
Can we reduce this noise using passive components? (i dont want to have to touch it all the time haha)
Anyway, thanks in advance if u can help
