Hi,
I don't know the answer, but backward integration is always stable. I know some forward integration algorithms will causing non-convergence problem. But I don't know why it is particular important in low power range ... Could you please help me?
If you need build accurate inductors, I suggest you do ADS or momentum. I know some PDKs do inductance extraction, but the kit designer told me it's not that accurate.
I have seen your other thread of PEX extraction. Yes, inductance extraction depends on the models provided by your foundry. I believe you need to contact TSMC for more info.
Yes, then my reply shows the way to go. Another way is to use skill script to draw and connect the whole array. You can do it fast if you are familiar with it. Otherwise, just use the method I mentioned for a simple array.
Starts from the definition: "The input offset voltage (V_{os}) is a parameter defining the differential DC voltage required between the inputs of an amplifier, especially an operational amplifier (op-amp), to make the output zero (for voltage amplifiers, 0 volts with respect to ground or between...
What do you mean by "using arrays"? Do you mean drawing a cap array? In cadence layout, you can draw one unit cap first then select and copy them. Then before you paste them, press F3 and you will get a window where you can change the number of rows and columns that you want to paste.
Sorry I don't have an answer, but want to share my experience.
Matched Length Constraint is the correct one to use, but would be hard to met the requirement. In Cadence, you can see the length of each segment of the connection, but not all of them. So matching them by hand requires a lot of...
I agree with Dominik, you have to first check which technology you are using. But it shouldn't be a problem as most process now use p-sub so PMOS is definitely in it's own n-well. Therefore, your input PMOS pair should be fine, but at a cost of larger area (you cannot share n-well with other...
Thank you so much guys for the suggestions. I am really considering to use a bipolar RF transistor to provide the current.
biff44, thank you so much for the comment on the measurement. I will pay attention to this problem next time. This size of the coil (build on a PCB) is indeed very small...
Dear goldsmith,
Thank you so much for your reply. I understand the matching is very important when connecting to an antenna. But since I am connecting to a serial LC circuit, I am not sure how to do the matching now as when in resonance, what left is only the resistance of the inductor which is...
Hello there,
I am designing an near field inductive link at 900 MHz. For some reason, I need to 1W at transmitting coil which is a serier LC circuit. I am trying to drive it with a 900MHz 30dBm Power Amplifier.
My question is, do I need to match the impedances of the PA and the LC in...
