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 ...

What does it really take to build a clean 1.28 GHz reference? Uncover the architecture decisions, noise trade-offs, and ...

Thus an RF oscillator using a tuned circuit can drift by many kHz over the period of its operation, and its timing can not be relied upon. Long before accurate timing was needed for computers, the ...

Ruggedized in an ultra-low vacuum for enhanced thermal insulation, the EX-423 delivers stability and RF performance ...

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 ...
