Portland, Ore. — Researchers at Cornell University have created the world's smallest mechanical oscillator that is capable of being tuned electrically. The nanoelectromechanical system (NEMS), which ...

A current-feedback amplifier is a well-known component with many uses. Its basic block diagram shows that its input stage is a voltage follower—in practice, a symmetrical emitter follower (Figure 1).

There are plenty of hobbies around with huge price tags, and ham radio can certainly be one of them. Experienced hams might have radios that cost thousands of dollars, with huge, steerable antennas on ...

Thanks to its low jitter and excellent phase noise, the RFX300 radio-frequency crystal oscillator is well suited for Sonet, synchronous digital hierarchy, asynchronous transfer mode, and wireless-area ...

Microcontrollers tend to consume other kinds of electronics. A project you might once have done with a 555 now probably has a cheap microcontroller in it. Music synthesizers? RC controllers? Most ...

Sonet, SDH, ATM, and WAN applications are the main targets for the RFX300 series (rfXO) of high-performance RF crystal oscillators. The devices feature just 3-ps RMS jitter, 0.5-ps phase jitter, and ...

Intended to accelerate next-generation RF innovations, the NI USRP X420 from Emerson is a software-defined radio (SDR) platform that addresses the demanding requirements of advanced radar systems, ...
