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, 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 circuit consumes power only if reverse polarity is applied. Unlike FETs or semiconductor switches, relay contact switches have low on-resistance, meaning that they cause no voltage drop between ...

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 ...

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

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 ...

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 ...

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.
