nobody is going to do your work for you. We will help out with specific question, but we won't write code for you. I suggest you do one of the following a) tell your boss you need help b) study more c) hire a consultant to do the job d) post the same question on stackexchange and have the notoriety of a post with a -100. ;-)
nobody asked "at which frequency??"...
Without any useful information other than symptoms, nobody is going to be able to suggest anything helpful. Things like who makes the fan, documentation, wiring diagrams, photos, etc... At least something more than two sentences (that contain very little information). Like there is no description of how you injected dc into the fan.
-60dB is 0.1%. -90dB is 0.003%. Few people can hear 0.1% distortion in music but a sinewave sounds a little like a buzzer. nobody can hear 0.01% or less. At fairly low frequencies an OPA134 audio opamp has 0.00008% distortion. A TL071 audio opamp has 0.03% distortion. A 741 or LM358 ordinary old opamp has about about 3% distortion.
nobody can help you with just scarce informations and a diagram at the size of a postage stamp :roll:. Show what you have, what you tried, what you expected and what you got instead. It won't work if you are not willing to invest at least a little of your own sweat.
nobody knows , that's still bother me.
nobody is going to do your homework for you. If you have a specific question then ask that question, instead of asking someone to help you.
Start with + input, the easy one. VIN+ = 2.5V*(100k/(25.9k+100k)) = 2.0V. Now ignore R2 since nobody's telling you input bias current. Though depending on op amp this could matter slightly. VIN- must equal VIN+. So now I(V1) must equal (2.0-1.3)/23.7K or 29.5uA. This must also be the current through R5, to 2.0V (on VIN-). So VO=2.0+29.
What is the reason? Please help me. If you do not have the uptake to realize that without presenting any code or picture nobody can help you, you will hardly note that there are other ways of debugging the program, such as systematically identifying what is and what is not working ( communication, display, etc... )
Neither; usually they're fairly lousy regulation (if any). nobody cares since they only have to charge the battery without burning it up (and the phone has some smarts about that, inside). But I have used many of them, with some added filter caps and a 3-terminal regulator, to make low cost (wall wart is free when the thing it powered, died) powe
I certainly hope nobody does your homework for you. Next time why don't you just say "Take my class for me and do my homework for me, so I can go do something I consider more important" :-)
This is not a Cadence issue. It's a PDK issue and any answer comes from the foundry, what they chose to model and check. They might set an arbitrary limit where they think "nobody (sane) would ever..." but that's some misplaced faith. Get the PDK. Read the rules. Your answer will be there, somewhere.
It's all about transition density, and gate by gate this is widely variable. Clock tree vs total, that's architectural. How much is always-clocked registers / FFs, how much is gated- clock, how much is combo logic? nobody's answer will be the same as yours, unless their chip design is the same as yours. Assessing the similarity of basis, for any
For analog blocks low voltage is "what you do because you must", not "what you want to do for analog quality". Ability to integrate trumps ultimate performance. Of course running off one cell or less, for a very long time has value in things like hearing aids, low-maintenance remote devices (IoT) and so on. nobody wants a +/-15V, 10mA op amp in
Not only finite (and unbalanced) switching times in the logic, but comparator rising / falling delay asymmetry can cause race conditions which turn into output glitching. In the larger picture the flash ADC data would be registered (nobody likes to work with unstable data) and the trick is to ensure that the strobe avoids the hazard regions. Thi
Most 18650 Li-ion cells do not have protection circuits built-in but some do. The protection circuit is usually in the laptop battery circuit, not in each cell. ebay sells mostly fakes and manufacturer's rejects. nobody makes an 18650 cell with as much as 6800mAh, it is probably 680.0mAh instead. One video of a fake shows a tiny 68mAh Li-Po inside
I see nobody responding so I'll suggest that while you're waiting, you find a copy of the design kit docs and find the mask levels descriptions and groundrules that pertain to this layer. That ought to be what anybody who uses the process, would be regurgitating on your behalf.
If you ask a power supply designer, +20% design margin on power switch voltage handling will get you only scorn. If this is a school project then maybe nobody will notice. Anyone whose reputation is on the hook for using your product would insist on more confidence I expect. And a die that nobody buys has pretty lousy manufacturing economics no ma
Probably the value in a timer but without the code nobody can tell you what and where it needs changing. Brian.
nobody knows the answer to you question? May I hypothesize? It seems that antenna is not isolated port but input, LO is another input and the other two ports output sum and difference of the two input signals. It seems that way by looking at diagrams for rat-race coupler published on
