Dear Friend,
I am using IE3D v 15. So, AEC is available. i have gone upto 3 layer.
My question is related to impedance measurement difference between linegauge and TLN of IE3D.
Do you have any idea about Asymmetric coplanar waveguides?
I also want to measure the impedance of...
Dear Friends,
I am designing Microstrip and Coplanar circuits using IE3D EM software.
I am using Lin-gauge in order to calculate the parameters like impedance, angle, width, Effective E.
When, i am calculating the same parameters through TLN parameters in IE3D then i am getting...
Dear Friends,
I am designing matching networks at 2.45 GHz. I am using ADS software.
I want to make use of series stub matching in my design.
But i am not able to find it in ADS schematic.
please help me so that i could do it.
Dear Friends,
I am designing matching networks. I have to design the matching networks to match the high imaginary impedance at 2.45 GHz frequency.
i need more than 100nH inductance at 2.45 GHz. I am able to get 34 nH maximum value of inductance from coilcraft. after this limit i am...
Dear Friends,
I want to realize some defected ground structures in ADS 2009 software. I am able to do this job with I3D software.
Since ADS is quite powerful software for Rf designing so i want to do this job in ADS.
Could anyone help me?
I would be happy to know your ideas even...
Dear Friends,
I want to design PCBs for wireless communication. I am working at 2.45Ghz.
I am familiar with normal PCB designing. But, i did not design PCBs at RF.
i need some design guides. Could anyone help me?
Dear Friend,
Both are same. In RFID field,we use charge pump approach in order to generate DC voltage at the output which is used in passive RFID Tags. Diodes and capacitors are used to make this circuit. Input RF amplitude is generally low. So, we need multiple stages of...
Dear all,
I am designing rectifier for RFID tags. I need to calculate input impedance and input power.
I did PSS analysis and Transient analysis. Since my rectifier is non-linear circuit. I need to match it with antenna.
So, i need matching networks. I am using cadence software with UMC...
Dear erikil,
Thanks for your reply. But i am not getting your point.
Could you explain in more detail?
There are many options in order to select technology (like TSMC, UMC, XFAB, AMS).
I have selected UMC 180nm RF CMOS. Is it ok. my application needs communication distance more than 10m.
I am designing RFID tags. I want to use low Vth MOS transistors in my design.
I need 50mV Vth. Which Technology is suitable for my design.
What do you think about Zero Vt transistor in UMC 180nm CMOS technology.
With Regards,
CS Gautam
Dear Friends,
I want to do AC Analysis of CMOS inverter. I am using 250n Technology.
I made one inverter (Ln=Lp= 250n, Wn=Wp=2.5u, Vdd= 5v) and got the gain 15. I did the DC analysis and got bias point 1.9V.
Now i want to increase the gain. So, i need to increase the number of...
I am getting the following error Fatal Error during simulation: "Cell0.sp" line 26 Missing MOSFET model definition for "NMOS" even though i have included ".lib "C:\Documents and Settings\RS62\My Documents\Tanner EDA\AMIS 0.5CFN\setup\models\C5X_mos.lib" typ" model file.
