Abstract

The paper presents performance analysis of an analog front end (AFE) for body-coupled communication (BCC) which is based on data transmission via capacitive coupling through the human body. The AFE designs by cascading differential preamplifier and Schmitt trigger. A flipped voltage follower (FVF) topology is used as part of the preamplifier design. The operation frequency of the overall system is mentioned as 10 MHz. The open loop gain is 24.01 dB and the close loop gain is 19.43 dB for this preamplifier. The input referred noise PSD is 8.69 nV/√Hz at 10 MHz. The system runs on a supply voltage of 1 V with implementation being done on 65 nm CMOS technology.
