Usually we use Shooting-Newton-PSS in Cadence and HB in ADS. Both HB-PSS and Shooting-Newton-PSS work with large signals, right? But I do not know the difference between the two methods. It would be wonderful if someone can tell me the difference, haha. Thanks anyway!
PSS simulation is Periodic Steady-State simulation. I wonder if it is similiar to HB simulation. Anyone can tell me the difference between these two methods? Thanks.
Thank you all! Sorry that I think i have missed something for making the problem clear. Here S22 is the return loss of the amplifier which has included the matching networks, and the impedence of antenna load is 50 ohm. The output power is got by PSS simulation, which is more than 20dBm. I have...
HI,guys,I met a confused problem in designing PA. The impedence of antenna load is 50 ohm, and simulated S22 of the PA is closed to zero, but the output power is accepted(more than 20dBm). I think if the output power is ok, it will be OK even if S22 of the PA is bad. Also, bad S22 is even...
HI! PLs. see the attached PDF file.I have some puzzles in reading this paper. I have marked my questions in the paper. Would u pls take a look at the paper and shed some light on it? Thanks in advance
hi, now I encounter the same problem. Anyone can tell me how to get the proper IIP3 values according to the measured results with the imbalance between IMD products? Thanks a lot!!!
Recenterly we worked on a 2.4G transceiver(IC). I wonder if the lines should be considered as transmission lines. According to transmission line theory, when the length of the line is comparable with the signal wave-length, it should be seen as transmission line. But I still feel that these...
Thank you! Still two more questions:
1.How about the stability in low frequency? Should i consider the stability from DC to the high band?
2. What kind of K value will be OK? I think it is not enough that K is just greater than 1, how about being greater than 1.05 or 1.1?
Thanks, but i still wonder about the frequency range in which the K value should be simulated and focused on. For the LNA with the band of 50M~1G, what kind of frequency range should be noticed? 1M~10G is ok or not?
Hi,
I have a question on the stability analysis on the designs of two LNAs.
The bandwidth requirement of one LNA is 50MHz-1GHz. Another one is from 10GHz-16Ghz.The attached two diagram is my K value stability analysis.
Would u pls. give me some advice on if my staboty analysis is OK...
