The other day Linda from Purchasing came to me with a problem: Lou from Operations needed to source a replacement for a shorted diode on a switching power supply. The darned thing was marked with a ...

Researchers have developed a capacitor with a metal-insulator-semiconductor diode structure that is tunable by illumination. The capacitor, which features embedded metal nanoparticles, is similar to a ...

Various configurations (Colpitts, Pierce, Clapp etc) are described in literature [Ref(1)]. Depending on the frequency requirements, various devices like MESFETs, pHEMTs, and HBTs can be used for VCO ...

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 ...

1. This circuit uses a JFET to bootstrap the cathode of the photodiode. It eliminates the effect of diode resistance and capacitance. This improves bandwidth and reduces noise, but puts a dc voltage ...
