Hi,

I was wondering what are the usual methods of amplifying a very short =
phase difference ? I would like to do some short range (< 20 feet) RF =
telemetry with a PIC by analyzing phase variance from several clocked RF =
pulses.

Any chance of using the RFpic for this ? I would like to make small =
battery operated transmitter nodes with different frequencies which you =
could "stick" a strategic points in a room and a mobile receiver unit =
which compares the various phase "errors" to compute displacement.

btw, thanks to all who participated in the 7805, overheating vs =
switching regulator thread. I ordered a few Power Trends PT5101 =
switching regulators from DigiKey and I must say I'm impressed! They are =
incredibly more efficient than the 78XX at high Vin.

regards,
