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 ...

In this paper, we present the results of a 6-year experiment in space that studied the effects of radiation in Gallium Nitride (GaN) electronics in geostationary orbit. Four GaN transistors in a ...

Beyond the use of optical frequency combs as precision clock sources in the optical region, researchers have developed a way ...

Microchip Technology is introducing its EX‑423 Evacuated Miniature Crystal Oscillator (EMXO). For space‑ and power‑constrained designs, it features ultra‑low phase noise. The compact, low‑power timing ...

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 ...
