High Speed PCB Layout

thadman · 8th May 2010, 04:46 AM

Could anyone recommend any resources for researching high speed PCB layout?

I'm aware that parasitic inductance / capacitance as a result of the PCB layout (ex. traces) has a significant effect on the stability of the control loop.

What grounding techniques are recommended for high speed circuits?

I believe the TI TLV3502 comparator can switch in 4.5ns and transresistance amplifiers are able to operate in excess of 100Mhz. However, I believe the limiting factor will be the PCB layout. What is a realistic high speed limit for discrete analog circuits?

Thanks,
Thadman

Hello

Use split planes for power, ground, and signal ground, and if possible use multi layer pcb.
