Human body communication

Purpose

For the better connectivity of various bio-medical and wearable applications, human body communication (HBC) which uses a human body as communication medium is considered as a promising candidate for body area network (BAN) because of its low channel loss. However, high-data rate of HBC is greatly limited by its band-limited and reflective channel characteristics. Our research covers a semiconductor transceiver design which overcomes those problem in an efficient (Power, Area, Speed) way based on LINK circuit technique.
