Voltage to Current Converter Makes a Flexible Current Reference -
09/18/03 EDN-Design Ideas: The voltage-to-current converter in Figure 1
can both source and sink current. The circuit is more flexible 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)
Voltage-to-current converter drives white LEDs - 06/27/02 EDN-Design
Ideas: 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
