Hi,
are you the author of the MSc. Thesis?!! Pleased to meet you, ALexandre!! (My name's is also the same!!); I've read your thesis a long time ago, and I mentioned your paper on my PhD dissertation (I'll have the viva voce in a month or so!!) .
Thank you for replying anyway!! I remember this...
Hi again! There are some topics I'd like to discuss with you all, relating to the DVCO descibed in the paper I've attached. First i'll review some issues that might help achieving a better understanding
1 The "periodically loaded transmission line" is used as an analythical framework in...
Hi again! There are some topics I'd like to discuss with you all, relating to the DVCO descibed in the last paper I've attached. The "periodically loaded transmission line" is used as an analythical framework in distribuited amplifier theory. In fact, in its essence the distributed tunable...
Yes! exactly what I meant, difference between theory/ simul. and real life behaviour. I just measured my oscillator, and i had very different results from what i've been simulating, and the individual frequencies are more affected by transistor parasitics than "the loaded transmission line" i...
I thank you a lot!
I'm sure you have already seen it, anyway I'll post the second reference as an attached file...my circuit looks pretty much the same as the one described in this paper, in terms of topology. Differences are :
1) I used a fixed width for the gate lines/ drain lines but...
Thanks for your answer!
did you ever actually try to build or at least simulate one? It is very interesting what you're saying, I've always felt that there's so many degrees of freeedom and unknowns, it turns out to be a difficult task in accurately predicting the oscillating frequencies.
Do...
Hi! I recently designed a distributed VCO with hybrid (discrete components + transmission lines) following the guidelines in Skvor-Divina paper (reference[1,2] is provided below) in the range 1-2 GHz, that worked good enough, meeting the design requirements in terms of frequency of operation...
