Abstract

A 1.3 pJ/b inductive coupling transceiver is proposed for Cm-range multimedia data transmission in mobile device applications. Its transmission time control (TTC) scheme and adaptive gain control (AGC) scheme reduce the energy consumption below to 1.3 pJ/b. Inductor with self-resonance frequency above 200 MHz achieves the data rate over 50 Mbps. The receiver sensitivity can be enhanced to increase the communication distance up to 7 cm by relative magnitude comparison between two nodes of the receiver inductor. The transceiver consumes only 65 Â¿W in total with 1 V supply.
