Hello ,
I am designing a pseudo diffamp with following specifications.
-Operating frequency of input signal : 1.4Ghz
-Supply - 1.1v
-Input swing vref+/- 150mV
-Vref - vdd/2 +/- 150mV
Max Vt of pmos/nmos in our technology is ~400mV
Currently i am doing it with folded cascode of standard pmos...
Hello all,
My question is ?
I have seen in may standards quoting transmission line impedance equal to 1.5pF per cm . How this number is calculated?
Is this value frequency dependent? transition dependent ?
Kindly help.
Suggest link to know more information about the same.
Thanks.
Hello,
I am doing simulation of an IO running at 200 Mhz. Load is given equal to 6pF with the following distribution :
- tx line of 3cm (PCB trace ) : so Tx load is 4.5pf ( 1.5pF per cm ).
- Z0 is 60 Ohms .
-1.5pF lumped at far end.
IO transition times are order of 2.5nS (...
