hi all,
I am simulating a CML buffer with 50 ohm Tx line in spectre, I am unable to understand one thing why two parameters are given there TD and PL , i think both relate some way or other to length of Tx line.
when i simulate the ckt with no PL i am getting good result but when it is disastrous with any non zero value of PL.
MY QUESTIONS ARE.
1. HOW TD AND PL ARE RELATED .
2. WHAT MIN LENGTH OF TX LINE SHOULD I CONSIDER ,FOR A DATA AT 10 gBPS
3. FROM WERE CAN I GET THE VALUE OF RESISTANCE AND CONDUCTANCE TO MODEL LOSSY TX LINE.
kindly help...
