AgeMOS model for reliability simulation
Hi dick_freebird,
After one month work, i have to say you are correct in some points.
I first get the NBTI parameters of TSMC 65nm LP technology. And then generate the model files required by Cadence RelXpert. A folded cascode op-amp with gain boosting...
From the DC operation points plot, i could say you make a small mistake on the bias current.
You are refered to Allen's book. That's no problem. Yet you need to make the bias current in T1a 1.2~1.5 times the bias current in T1 plus or T1 minus, not the bias current in cascode 1.2~1.5 times...
AgeMOS model for reliability simulation
Do you means it makes no sense to have AgeMOS model?
Now i'm involved in a project which want to inprove the analog front end circuit reliability through periodic tuning. I need to varify if the idea is work or not. That is why i need reliability...
Does anyone know TSMC or others has AgeMOS model for their technologies?
i want to do some reliability simulation using Cadence RelXpert. The technology is prefered to be TSMC 65nm. The problem is that i need the AgeMOS model for the simulation. I don't know if the AgeMOS model has been...
Re: Jitter Issue
Jee is the edge-to-edge jitter. It is the variation in the delay between a triggering event and a response event. When measuring edge-to-edge jitter, a clean jitter-free input is assumed. Edge-to-edge jitter assumes an input signal, and so is only defined for driven systems. It...
I found a interest fact about NS LM723. The output noise from LM723 is well from 100Hz to 10KHz, but raised quickly above 10KHz. Finally at about 1MHz, the noise begin to go down again. So i recommend to use a large capacitance parallel with a smaller one to bypass the output of LM723.
About my...
Re: Can you give some advice on suppress noise from regulato
Big capacitor is not possible. Its will be at least several hundrd uF and i can't place it.
If suppress is impossible with brief circiuts, can I design a simple discrete transistor regulator to instead 723? I don't care about many...
I am designing a low phase noise crystal oscillator. The noise of the supply(need 9V and 10mA current) is critical! So i need to suppress the noise from regulaor to about 7nV/sqrt(Hz) noise floor(about 100 or 1k to 1MHz). The 723 regulaor output noise is about 20uV(from 100 to 10kHz). It's much...
How to extract parameters of XTAL(Crystal) in ADS?
I have measure the impedance--frequency curves of XTAL. But i don't know how to extract Cx,Lx,Rx and C0 by software. I heard that gray-box in ADS can do this. Does it true? I can't find any help about gray-box. By the way, can ic-cap do this...
Emitter resistor with bypass capacitor works well in low frequency, but when go to RF, it has problems. I think some points like this can't be obtain from basic electronics books.
So i agree with that Agilent App Nots--Microwave Transistor Bias Considerations is the best material i can find.
I'm study the book <<Microwave Transistor Amplifiers>>, but still confused with transistor Bias. Can you suggest some good books or papers study about full-scale transistor bias circuits with thorough analysis?
