Hello,

I am Suki, currently studying in BCU which is located in Birmingham,UK in BEng Electronic Engineering.

I am doing my project entitled Near Field Communication. I am currently under my deep investigation regarding this title. I have found a ppt that relates to this project, but I really want to know, what type of software can be used in order to design the circuit, because, while I am designing my circuit in Orcad pspice, some of the component needed for NFC are unavailable in Orcad pSpice.

Therefore, I really hope that somebody who have done this project can give me some advice in designing the circuit.

TQ.

Regards,
Suki

please read https://seminarproject.net/Thread-near-f...ull-report for getting more information regarding Near Field Communication

if you want best support for NFC (Near Field Communication) circuit programming then check the page http://www.libnfcdocumentation/introduction ...
i hope will resolve the problem...

to follow up the communication with suki ..i have added the content of conversation with my friend dilip (a circuit expert)...


i think you try Proteus to impliment the circuit...
Proteus has an in built simulator
it can be used to draw the schematic (the ckt dig), develop the PCDB, as well simulate ckts
unlike, in orCAD, we can only draw the schematic and develop PCB
unlike, in orCAD, we can only draw the schematic and develop PCB
PSpice is actually another program
PSpice is the best when considering discrete electronic components like transistors, resistors, capacitors and inductors
but lack some quality in simulating chips
i mn, ICs
Proteus is good for certain ICs like PIC and 8051
common drawback is that, both may not be having simulation models for certain ICs
i think tht might be the problem with the circuit
tht u gave
the IC tht is being used in the trnsmitter section is not clear

one is MAX232
the other one
also, the op-amps used
(triangles)
the resistors' value is also not legible
for both
its hard for me to simulate without getting the exact values
the big IC used in receiver section is NE564
i think tht doesn't have a model either on PSpice or Proteus
in order to simulate those, we ll have to create a model for each of the IC
refer the datasheets of each IC and try to make an equivalent ckt for each IC
for example, NE 564 = http://www.datasheetcatalogdatasheet/philips/NE564.pdf
the equivalent of tht is given in page 6
58 transistors, 50 diodes, and numerous resistors!!


conclusion :
need better clarity circuit image to analyse again
