| Abstract(in English) | The visible light communications that communicates by modulating the light of illumination, which is the existing infrastructure, attracts attention. So as to improve the speed, to increase the bandwidth, and to miniaturize hardware of this communication system, improvement in the transmission speed by a single LED for lighting is important. The transmission speed of an LED is greatly restricted by the carrier that remains in junction capacity. Therefore, the carrier drawing-out circuit using GaAs FETs and a discrete element were proposed and, therefore, improvement in the speed of the LED drive was attained. However, the proposed circuit is not practical circuit composition, power consumption increases. We compose the practical circuit with 0.18-μm CMOS process inverter circuit and propose circuit composition to lose power consumption in the carrier drawing-out part. Therefore, an optical measurement shows that the fall time decreases from 63.0 to 12.5 ns (decreases to one fifth), error free NRZ PRBS signal bit rate of BER has been improved from 19.5 Mb/s to 43.1 Mb/s(increases to 221%). |
