If we replace the potentiometer VR1 with an AC signal plus DC bias signal in any of the previous Figures 3 to 17, the voltage controlled attenuators can become an amplitude modulator circuit instead.

Every high-voltage electrical application in today’s world requires monitoring, whether it’s on the electrical grid and making sure that the nominal current is flowing downstream, or in a motor and ...

The local thermal conductivity in certain oxides can be precisely defined by a voltage-biased AFM tip, a new CiQUS study shows Overheating in electronic devices affects how it works and how long it ...

Researchers have devised a new approach for controlling light in a silicon chip by bringing the concept of spatial light modulation to integrated optics. Silicon photonics are forming the backbone of ...

Scientists at The University of Manchester have discovered a new method of creating optoelectronic circuits using graphene and other 2D materials that are much smaller than their current counterparts.
