碩士 === 國立暨南國際大學 === 電機工程學系 === 100 === This thesis proposed a digital dimming control circuit for RGB LEDs . We make the circuit have two functions that are low speed(RGB) and high speed (white light). We use a method “pulse width modulation (PWM)” to control the RGB pulse width and make color change.We use RGB circuit to compensate white light and increase its CRI and CT. We simulate the function of RGB colors and analyze its circuit character using HSPICE. Verify with Calibre DRC (Design Rule Check)、LVS (Layout vs Schematic)、 PEX (Post Layout Extraction) made by Mentor Graphics Corp, layout with IC made by Cadence Inc., implement the circuit structure by “TSMC 0.18um MIXED MODE (1P6M，1.8V/3.3V) process”.
