For battery-powered circuits, it is easy to build an ultralow-current crystal oscillator designed around a 32.768-kHz crystal. This crystal is common for real-time-clock circuits. Because these ...

EM Microelectronic, an electronic systems company of the Swatch Group, introduces the EM7604, a low-power CMOS crystal oscillator circuit. The EM7604 is intended to be used with a 32.768 kHz tuning ...

There are many crystal oscillator configurations, but the circuit you are most likely to encounter if you work with digital circuitry is the Pierce oscillator. You’ll find it implemented using ...

Designed to control the frequency of crystal oscillator circuits, the 3022 series of high-ratio, hyperabrupt varactor tuning diodes is designed to deliver a dc bias control voltage from -0.3V to -4V.

Although oscillators are critical components in most electronic devices, designers needn’t design oscillators themselves in most cases, because the device contains a great deal of the oscillator ...
