I want to build a circuit using a transistor are a few light up my LEDs.Now,LEDs are a constant current source.This seems simple.However ,i have a situation:
1.The input DC voltage from the supply can vary from 16Volts to 32 Volts.
2.I want to build it using a single transistor,i.e., a linear circuit,"without switching"
The voltage can be any nominal voltage,say 20Volts..however a variation in the range of 16 to 32 or any abnormal voltage for that matter should not cause any change in the current to the LEDs..
I'll be glad to receive suggestions/inputs as to how to go about with this.
Thanks
