Abstract

In this paper, the design of a programmable mixed-signal electronic circuit to control the light output of a red-green-blue (RGB) light emitting diode (LED) to be used in an optical fiber sensor system is presented and discussed. The LED is to be used as a light transmitter (light source) within the sensor system. The output of each LED color is to be independently controlled using either a d.c. current or a pulse width modulation (PWM) encoded current. The idea for, and architecture of, the mixed-signal electronic circuit design is considered as both a discrete implementation using off-the-shelf components and the concept for an application specific integrated circuit (ASIC) solution using a 0.35 µm complementary metal oxide semiconductor (CMOS) fabrication process. In this paper, the design operation principles, circuit architecture, simulation results and hardware requirements for this LED driver circuit are considered.
