If you have a Zener diode (ZD) of unknown characteristics or if you want to use reverse-biased transistor junctions as ZD, the zener voltage and performance can be tested with this simple circuit.

In production, this may be replaced with a zero Ohm resistor. The open circuit protection circuit shown utilizes R9, causing it to serve an additional function, in conjunction with Zener diode D2. In ...

Using simple components such as oil, salt water, lipids and proteins, plus routine genetic engineering techniques, it is possible to create simple nanofluidic circuits.

A simple Zener-diode stabilization network circuit using D2 supplies a voltage of 100 V dc. The value of R1 depends on the source voltage and must be calculated with the equation, R1 = (V ac −s ...

By using a constant-current source along with a ratiometric DAC configuration, the output intensity of a laser diode can be carefully set and controlled using this simple circuit ...

The circuit is simple enough: it uses a capacitor, a resistor, and a pair of diodes (one of them a zener diode). He uses this basic circuit to drive simple regulators with input and output filter ...

Driving laser diodes, however, requires a greater degree of care than when dealing with LEDs, for example. Laser diodes are more sensitive, particularly with regard to spikes and the effect of ESD. A ...

Most plastics don't conduct electricity, though that hasn't stopped researchers from trying to build plastic computer chips.
