Abstract

A 200-Mbps 0.02-nJ/b dual-mode inductive coupling transceiver is proposed for cm-range multimedia application. The inductive link geometry and the advantage of the pulse-based inductive coupling are explained. In this paper, the parallel capacitor connected with the TX inductor, the intersymbol interference (ISI) reduction scheme, and the pulse generation scheme are newly proposed. The parallel capacitor connected with the TX inductor increases the transmitter impedance so that it enhances the transmission distance by twofold, and the ISI reduction scheme pushes data rate up to 200 Mbps. Moreover, the pulse generation scheme reduces the energy consumption as low as 0.02 nJ/b. Maximum data rate and energy consumption are achieved in simulation. The transceiver occupies 0.012 mm2 in 0.25-µm CMOS process.
