Vishay Intertechnology introduced a new tricolor LED that provides luminous intensity to 252 mcd at 5 mA for RGB displays and backlighting. Featuring common anode and separate cathode connections for the red, true green, and blue LED chips inside ...

This two-part Design Idea (DI) follows on from a couple of previous articles relating to 100-Ω platinum resistance temperature detectors (Pt100 RTDs). The first of those (which we’ll call Ref 1 ) used a simple current-driven bridge to give an ...

Modern high-speed RS-485 data links are pushing the envelope to the absolute breaking point with regards to data rate versus cable length. Applications include position encoders, traffic monitoring, seismic networks, and GPS transceivers. Data ...

In this Design Idea (DI), the classic Schmitt-trigger-based RC oscillator is “hacked” and analyzed using the simulation software QSPICE ( Ref. 1 ). You might reasonably ask why one would do this, given that countless such circuits ...

Nedjeljko Lekic works at the University of Montenegro, Department of Electrical Engineering. He holds a PhD in electrical and computer engineering from the University of Montenegro. He has been working on designing identification systems based on ...

Zoran Mijanovic has been working as a professor with the electro-technical faculty at the University of Montenegro. He is engaged in industry mostly to find and design solutions for novel needs. He has designed many microcontroller devices for ...

Applications such as audio equalizers require bandpass filters with a constant maximum gain that's independent of the filter's quality factor, Q. However, all of the well-known filter architectures Sallen-Key, multiple-feedback, ...

The circuit uses a very inexpensive C-MOS IC that is connected to a small photodiode. Using a unique inductive feedback network, the circuit provides high sensitivity under high ambient light conditions. It is a great circuit when you want to ...
