Here are 4 simple 12V power supply circuits with output voltages around 12V. First power supply circuit is built with BD139, one zener diode and a few passive components. Each of the schematic is very ...

Laser diodes are enjoying ever greater popularity in sensor engineering and measurement technology thanks to their high optical output power. One of the advantages of this is that a wide optical range ...

Many embedded systems require a stable, low-noise DC reference. This reference can be a stable current or voltage source. These references are used in many ways. Some typical uses are listed as ...
