This circuit is from the Motorola Linear Databook of 1990 and can be implemented with other operational amplifiers. The power supply must be symmetrical.
The circuit shown in the figure consists of a system for driving white LEDs (WLEDs) at low...
Any operational amplifier can be used in this circuit. The 741 is the most common. Power supply must...
This simple circuit needs a high gain stage to compensate for losses. It consists of a passive tone...
