Yes, you can do this, it needs you to derive / extract the LRCM mesh accurately and impose likely aggressors and so on. I've been able to make DJ appear in Spectre analog_extracted based simulations, C-only, from long lines routed in proximity. I have no idea whether your tools and PDK support inductance (let alone mutual). But the 'scope looks ve
you need to get datasheet of the ferrite........few softwares will know what ferrite you they wont be able to assess your core losses. Generally...make sure 1...dont saturate 2....dont overheat core with core loss 3....use enough strands to avoid skin effect problems 4....proximity mindful of it
Don't know if these examples touch on what you're looking for... * A classmate once showed me his proximity alarm, attached to a doorknob. If a hand touched the doorknob, the circuit buzzed. Or if it got within a fraction of an inch. I failed to see how it could work since there was no path for current. I'd been taught electricity needs a complete
Presume you mean 13.56 MHz. Permitted power at 13.8 MHz would be very low. First you'll specify the intended operation. "Localization" sounds like a wider range. Most 13.56 MHz tags are designed for proximity range (usually below 10 cm), e.g. NFC and ISO 14443/Mifare. ISO 15693 vicinity tags can achieve a wider range, but only with rather bulky
Hi All. I have a project where I need to make a Bottle Cap Sensor which will Alert when the Cap is open. Can anyone advice whats the best way to do it. I thought about IR Tx-Rx based proximity but it will consume more power where my project needs low power consumption. Also the bottle will be glass made transparent so I can not use LDR to detect
Hi, I am using a NPN type and PNP type inductive proximity and optical sensors in my project. 134035 The sensor connections will be given at the customer end. Even after documentation and legend in PCB, I am afraid if the customers giving the wrong connection. Say example: Power of sensor to signal in PCB likewise.
This lovely and cheap IR works by proximity...when you wave your hand it comes on...time on-off is adjusted by VR1 pot. Can anyone please suggest how to modify the circuit to make it work like wave with your hand wave-on..then wave-off...?? the IC used is 4093 which is NAND gates 132786
Should I add ground wire between U1 and 3V LDO ? . The answer is, IMHO, a bold NO. But you should also pay attention to the comment and suggestion made in #7. If you care for EMI and noise pickups, you should run the 3V cable in close proximity with the 5V cable and ground. If you have signal (analog) that are nois
Suppose I have 2 hard macros and both of them do not have any pins facing each other. In such a scenario, can I keep those 2 macros at close proximity? Or is there any minimum distance criteria even if there are no pins on the face to face sides of the hard macros?
Hello everyone, I have a quesion about well proximity effect(WPE) in tsmc65. I have an issue with WPE. When i create Calibre view and compare the post layout result with schematic I am observing a huge difference. I found that it occurs because of that in the schematic "WPE" is off and it will be on for Calibre. The most interesting part is
How do you approach the metal? There's little magnetic coupling to the zone above (in axial direction) the bobbin core. For considerable eddy current generation and oscillator damping, the main field must perpendicularly hit the metal surface. Industry standard inductive proximity sensors often use P core halves (e.g. Feroxcube PH se
One problem is that you did not mention if your anechoic chamber is specified for your frequeny of interest. Locating antennas so close as less than 10 wavelengths does introduce large errors due to coupling, ground proximity, etc. The best solution is to use an open range for such low-frequency antennas. The distance
Skin and proximity effect will be always modeled in an AC magnetic or full EM simulation when you set material conductivity correctly. Meshing matters of course.
Hi to all, I have using the M12 Inductive proximity sensor, which having the 4mm sensing distance. If i want to increase the distance means, what i should do? Is there any sensor having larger sensing distance. May i need 15mm sensing distance.. Thanks,
I know there are papers on improving characteristics of microstip antennas by putting a slot in ground planes to increase characteristic impedance but I haven't seen them use couple two traces from board to board.
12v cannot give you shock, output of inverter can give you shock though. Mind you, if you did get a shock off a 12v source, then it may have been a capacitive shock due to the 12v common getting induced up to high voltage by its proximity to the inverter. Usually there is enough leakage in the components that span the isolation barrier to stop thi
Hello, I am going to simulate a proximity sensor based on measuring fringing capacitance in CoventorWare. However i can't find anywhere if CoventorWare is able to simulate such capacitance, or maybe just the direct one. Thanks for anyone who can anserw my question.
Hi Guys! I'm working on a project, I have a device with a SIM808 and a embedded microcontroller (STM32). I want to create a simple bluetooth system to do a "role call" of objects in the proximity. My idea was to use my device as a beacon, and small BT tags which I can just use their serial number to check if there are reachable or not. I c
Hello all. I am confused by one layout dependent affect. I know about: "Poly-to-Poly Spacing Effect" (=PSE), "Length of Diffusion" (LOD =STI ="Shallow Trench Isolation" effect) "Well proximity Effect" (WPE). But what may bring into layout the minimum "channel - to - bulk_contact" spacing? (Please see attached picture)
As said, it's a capacitive touch sensor. With respective high sensitivity, it works as a proximity switch. If it's optical, it won't need spring contacts.
