Multi-stage light emitting diode driver circuit |
摘要 |
A multi-stage light emitting diode (LED) driver circuit is provided. The circuit includes a driver transistor coupled to an LED. The LED is coupled at a drain of the driver transistor and the driver transistor drives current to the LED. A first transistor stack is coupled between a gate of the driver transistor and ground. A first inverter stage is coupled to a common gate of the first transistor stack. The first inverter stage is further coupled between a high voltage source and ground. A second inverter stage is coupled to a common gate of the first inverter stage. The second inverter stage is further coupled between the high voltage source and ground. The circuit further includes a first transistor coupled between the high voltage source and gate of the driver transistor. The gate of the transistor is coupled to the first inverter stage.
