And here it is, modelled using LTSpice. It is the same circuit as the classic simple precision rectifier (set to pass the negative half-sine), but with the non-inverting input of the op-amp connected ...

A diode is a device that allows current to flow in one direction but not in the other. This ability makes diodes useful in many applications, including converting AC to DC, regulating voltages, and ...

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 now in clinical trials).

The lowly diode, a device with only two leads, can nonetheless do many things. Diodes can detect, rectify, suppress, emit light, detect light, change capacitance, emit microwaves and more. This wide ...

This video explains the function of diodes and how they are used to control the flow of electrical current in electronic circuits. Diodes are essential components that allow current to move in only ...

Beware! The behavior of a part outside its operating specifications is not always predictable. Beware! The behavior of a part outside its operating specifications is not always predictable. In my ...

In the realm of modern electronics, semiconductor diodes have emerged as fundamental components with diverse applications. One of their pivotal roles lies in the fields of rectification and voltage ...

The most demanding component in terms of high-frequency operation on an RF-ID tag is the rectifying device: this device needs to be able to charge a storage capacitor providing quasi-d.c. power supply ...

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

Scientists working at the Stanford Institute for Materials and Energy Sciences (SIMES) claim to have created a molecule-sized electronic component just a few nanometers long that conducts electricity ...

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 now in clinical trials).
