  • FET current regulation of LEDs
    Patent number: 6933707
    Abstract: Field Effect Transistors (FETs) are used to regulate current in a light emitting diode (LED). FETs are fundamentally voltage driven devices, where output current is governed by junction voltage. Since junction voltage can be controlled with little or no support circuitry, FETs present a solution to current regulation where cost, complexity, and perhaps even size are important.
