This tutorial explains the primary design considerations to be addressed in a design of a simple crystal oscillator using AT-cut crystals. The basic qualities of a crystal oscillator and factors that ...

Today, the majority of electronic circuits (including microprocessors, microcontrollers, FPGAs, and CPLDs) are based on clocked logic, requiring a timing source. Depending on the frequency accuracy ...

In practice a crystal designed for overtone use will have resonances at odd multiples of its fundamental frequency. Thus for example an overtone crystal with a 10MHz fundamental frequency would also ...

Appropriately cut quartz crystals can be used as high-quality electromechanical resonators. Their piezoelectric properties (voltage across the crystal deforms it; deforming the crystal generates a ...

At SiTime, we often hear from many customers when they have crystal design issues such as cold startup failures, oscillator circuit problems from mismatched crystals, or failure to pass EMI tests.

Abstract: This paper proposed a 3rd harmonic crystal oscillator that implemented in a BJT architecture with voltage loop tuning. The design integrated Negative Capacitance Field Effect Transistors ...

Fig 1. This Pierce-series resonant oscillator can reliably start at supply voltages as low as 2.4 V. It also draws very low current, ensuring long battery life. Fig 2. An oscilloscope photo shows the ...
