Voltage-to-current converter drives white LEDs - 6/27/2002 Issue of EDN
You sometimes need to drive a white LED from one 1.5V battery. Unfortunately, the
forward voltage of a white LED is 3 to 4V. So, you would need a dc/dc converter to
drive the LED from one battery. Using the simple circuit in Figure 1, you can
drive one white LED or two series-connected green LEDs, using only a few
components..... [Design Idea by Susanne Nell, Breitenfurt, Austria]

Voltage-to-current converter makes a flexible current reference -
18-Sep-03 Issue of EDN The voltage-to-current converter in Figure 1 can both
source and sink current. The circuit isflexible than some traditional current
references that require different topologies for current sourcing and sinking.
Also, you can easily adjust the value of the current reference by simply adjusting
the circuit's input voltage..... [Design Idea by Art Kay, Texas Instruments,
Tucson, AZ]
