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 researchers created simple diode-based AND/OR logic gates from these circuits and incorporated them into pulse modulators, which can encode information by switching one input signal on or off ...

Atomtronic analogy to a simple diode circuit. The atomtronic analogy of a diode formed from the joining of p-type and n-type semiconductor materials. Electrons are replaced by ultracold atoms, the ...

The circuit, including the indicatingmeter, can fit into a small housing,such as an empty 20g glue-sticktube. An ordinary 1N4148 silicon signaldiode serves as the temperature sensor,exhibiting ...

The diode conducts only when a lower voltage rises above a higher one at turn-on, but not if a higher voltage were to increase above any lower voltage, because the diode is reverse-biased. A preferred ...

Reading through the app note, the transient response to changes in voltage is less than 10 usec and the deviation is small. That seems pretty good for something like a laser diode.

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

This circuit was designed to meet a medical application’s requirement to drive a laser diode with reasonable precision and a minimum of components and footprint (the device is ...
