Hi, I've successfully been able to cosimulate via Ptolemy an HDL component I designed with other ADS blocks using HDLCOSIM component single input port and single output port. However, I need to use multiports and the manual says that it is supported as string arrays.
When I declare the outputs...
Hi,
Can someone provide me with links to introductory material on optical ICs? I'd like introductory information (more qualitative than quantitative) on waveguides, TE/TM modes, semiconductor lasers, LEDs, optic couplers, interferometers Mach Zehder, Fabry Parot filters, AWGs, Bragg gratings...
agilent ads 2009 path
I discovered that ADS2005A needs Matlab6.5 or above to cosimulate. However, Matlab6.5 or 2007 don't run on Vista. Matlab2009 does however.
I haven't got Matlab2009 so I don't know if it will run with ADS2005A.
agilent ads help
I need to re-simulate some old circuits that I designed (4-5 years ago) using ADS and matlab cosimulation. I haven't used ADS or MATLAB since, so I am quite rusty.
I installed ADS2005A and MATLAB5.3 on Vista and they both work fine when they are used separately. However, when...
audiometer using labview
Hi, I need to design an audiometer for a class project using Labview. I started to search for relative standards and methods to perform audiometry so I can start drafting the specs of the audiometer first.
I found that I need to check certain standards such as EN...
Re: about "MIMO"
Contrary to what may be reported, MIMO is *not* antenna diversity, beam forming etc. There are many pseudo-MIMO products out there in WLAN but not a real MIMO yet.
MIMO takes advantage of fading. It doesn't try to 'fix' it. A 2x2 MIMO system for example outputs different data...
I am searching for any online reference (thesis, ebook) that will cover the basics on RF simulation algorithms such as Harmonic Balance, Shooting, Fast algorithms etc.
Any input is appreciated.
Thanks for your ideas!
Converting to voltage would create extra overhead in my circuits and probably reduce my dynamic range. I wish to maintain a current mode design where I could.
I have found a reference that shows a current mode solution and I will try it. It's in a 1995 paper by Coggins...
Isn't AC coupling for voltage signals?
Anyway, I am talking about current-mode circuits. It turns out that if I can keep the common mode current within tolerable limits, I won't need to cancel it, although it would be nice to be able to.
I'd like to perform an addition of differential current signals in order to feed the resulting differential current signal into a gilbert-based multiplier. How can I perform this addition? Simple KCL won't work on differential signals because the common mode needs to be cancelled.
Thanks for any...
Thanks for your replies. Sorry I wasn't quite specific.
The QAM modulation (and demodulation) is done digitally and afterwards that I/Q is combined digitally, oversampled and then converted to analog at an IF freq of let's say 30MHz using eg @D9856.
(Taken from @D: The @D9856 integrates a...
