Subject: [SI-LIST] AC coupling hspice simulation
Hi,
I'm running some HSPICE simulation on a AC-coupled diff pair @2.5Gbps.
One problem I have is to deal with the RC constant effect due to the
series capacitance. If I reduce the capacitance value, the settling time
gets shorter but I also distort the signal significantly since the cap
act as a high pass filter. But if I use the designed capacitance, the
simulation running time gets unrealistically long to allow the waveform
to settle. Wonder whether any of you can share your thoughts/experience
on this.
Thanks
Perry
