How to use negative feedback to regulate output power from a laser diode using a simple, single op-amp based circuit ...

Here is a detailed view of reverse polarity protection circuits for safeguarding battery-connected automotive systems.

This circuit topology enables the amplifier to achieve a 4-MHz bandwidth with 60/spl deg/ of phase margin. The output voltage can swing to within 50 mV of each supply rail. An "on-demand" base current ...
