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 ...

[Paul] likes a precise oscillator. His recent video shows a crystal oscillator with a “watch crystal” and a CMOS counter, the CD4060. Using such a circuit can produce very stable frequencies and since ...

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.

Called SiT8021, power consumption is 110µA for 3MHz, and the device is available in chip-scale packages (CSPs) as small as 1.5×0.8mm. The MEMS part is a 524kHz double tuning fork resonator (see ...

Crystal oscillators are incredibly useful components, but they come with one little snag: their oscillation is temperature-dependent. For many applications the relatively small deviation is not a ...

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 ...
