I'm new to HFSS. For simulating planar dipole RFID antenna using HFSS, I noticed that lumped port is used usually, and the lumped port impedance is set to the conjugate value of the chip impedance.
My question is:
Because RFID antenna is directly connected to the tag chip for cost down, then...
Because RH7.3 and RH8.0 cannot support my new computer, I installed RH9. Then I mounted the !c5033 CD1 under /mnt/cdrom. When I run the SETUP.SH ( such as /mnt/cdrom/SETUP.SH or went to the /mnt/cdrom dir and run ./SETUP.SH ), there's an error said:
bad interpreter : No such file or...
I have mounted the USB memory stick successfully, and I can see the files in it.
But there is another question:
When I copied files from the usb memory to harddisk, after some time reading files, the error infomation was reported : Input/output error. And when I use "ls" command to check the...
Re: Why Phase Noise in CMOS LCtank VCO is better than the Ri
The quality factor of the ring osc is about 1 (Q=the ratio of the energy stored to the energy dissipated per cycle), because in one cycle period, the energy component (the capacitance) is charged in one half cycle and discharged in...
I noticed that in the above design, the loop filter is already 3rd order.
For integer-N frequency synthesizer, the spurs occur at frequencies (and it's harmonics) of the PFD. This is because the outputs of the PFD turn on and off the charge pump at the same frequency. So you can increase the PFD...
It's hard to integrated so large caps in IC technology. For the popular technology now, such as 0.18 micron to 0.35 micron CMOS technology, the unit cap value of MIM cap is about 1fF/um^.
When I run a example provided by !c50 (spiralind_example of the rfExample lib) using $pectre, the output log file gave me the following message:
Error found by $pectre.
Unable to run circuit preprocessor (/lib/cpp).
No such file or directory.
$pectre terminated...
There are my questions:
1.
When I click "Setup-->Simulator/Directory/Host", "hsp!ce" is not listed in the simulator's menus, but there is a simulator named "hsp!ceS", I wonder that 1) Is there a "hsp!ce" in the simulator's menus when clicking "Setup-->Simulator/Directory/Host"? 2) What program...
I have installed several softwares under linux OS. And I merged all lic files into one file. Then I start lmgrd:
lmgrd -c <lic_file> -l <logfile>
where <lic_file> is my new lic file.
But when I check the log file, I got the following message:
...
Trying connection to <host>
