This crystal is common for real-time-clock circuits. Because these circuits must operate at all times, achieving the lowest current draw possible is mandatory. Traditional gate-oscillator circuits—the ...

Figures 1a and 1b show block diagrams of a MEMS oscillator and a crystal oscillator circuit. The MEMS oscillator is more complicated.

Enter the oven controlled crystal oscillator, or OCXO. ... Still, it is interesting, and we always enjoy watching anything that gives us more intuition about the behavior of circuits or, ...

Crystal Overtone and Spurious Modes: Crystals can offer many resonant modes that can be exercised by proper design of crystal oscillator. The major response and mostly desired one is the “Fundamental ...

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.
