This application note presents the need to use an external Pierce oscillator to replace the RTC oscillator circuit that makes EP93xx susceptible to on-chip noises. It describes the implementation of ...

Everyone interested in analog electronics should find some value in this post. Of course, an effort has been made here to make the content understandable to relative newbies. Forget about complex ...

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 ...

What is a crystal oscillator's impedance? A look at the Pierce oscillator topology. How to generate negative resistance. An alternative approach to determining a crystal oscillator's impedance that ...

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 ...
