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 ...

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 ...

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 ...

If you've ever designed an RF oscillator, you've probably encountered squegging. Sometimes called "motor boating," squegging causes oscillators to start and stop at frequencies much lower than the ...

IN this method the frequency of a radio-frequency oscillator is modulated by a sinusoidal audio-frequency voltage, and the resultant radio-frequency voltage is applied to a transmitting quartz ...
