Dear All,

I am urgently doing a final year project contactless smartcard. I have read some paper on that. The technique is to use magnetic coupling as a channel, use ASK to send encrypted data. Digital Logic is no problem for me, but the interface on modulation/demodulation on VLSI is hardtime for me, can anybody help me on these aspects?

1. ASK Modem circuit (or how to design)
2. Linear Regulator Circuit

Please help me, coz' I have a really hard time searching these material on the web or in my library!

Thanks a lot!
