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 ...

Another great crystal oscillator circuit with BB139, a 2-nd harmonic quartz crystal and one BF214 transistor. So, the Q quartz is half of the desired transmitter frequency, L1 has 24 turns, 0.08mm Ø ...

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.

This project details the construction and observation of a simple crystal oscillator circuit designed to generate a clock signal around 16 MHz. The oscillator is built using a 16.000 MHz crystal, a ...

A very simple DIY crystal oscillator circuit which use a quartz for frequency stability and a good rf transistor. Use a 2-nd or 3-rd harmonic crystal, for example if you want 100MHz use a 50MHz or ...

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 ...

Abstract: In this paper, we propose a new structure for the cascode crystal oscillator which is suitable for integrated circuit realization. The cascode crystal oscillator is composed of a Colpitts ...

[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 ...
