An improved light element driver employing two transistors, one capacitor and one grounded resistor, is presented. It also has the fewest number of possible components and can drive a red light-emitting diode with a supplied voltage as low as 0.8 V. Its power efficiency is about 70% to deliver to a light-emitting element at 1 V supply voltage. © 2002 American Institute of Physics.
