Enhanced edge detect power line communication

A system, comprising:

• a first device including a first set of contacts;
• and
• a second device including a second set of contacts, the second set of contacts adapted to electronically engage with the first set of contacts of the first device to form at least a power and ground lines connection;
• each of the first device and the second device including circuitry for providing data over the power line connection between the first device and the second device, the circuitry comprising:
• a power line;
• a ground line;
• a transmitter line carrying data signals;
• a capacitor coupling the transmitter line to the power line at a connection point, the capacitor configured to filter DC components from the data signals and output a filtered signal that is carried to the power line;
• and
• a receiver comprising a first field effect transistor and a second field effect transistor, the first and the second field effect transistors configured to detect the filtered signal, the first field effect transistor configured to detect positive pulses of the filtered signal and the second field effect transistor configured to detect negative pulses of the filtered signal.
