Third-overtone crystal oscillator

The first thing to understand is how capacitor C1 is related to the resonance frequency f of the circuit. It appears that selecting a frequency allows for the automatic determination of the necessary value for C1. There are uncertainties...

This circuit oscillates without the crystal. When the crystal is included in the circuit, the frequency will match that of the crystal. The circuit exhibits good starting characteristics even with low-quality crystals. This circuit design features a basic oscillator configuration...

An electronic circuit consists of individual electronic components such as resistors, transistors, capacitors, inductors, and diodes, which are interconnected by conductive wires or traces that allow electric current to flow. The sine wave or sinusoid is a mathematical function...

This is a sine wave oscillator circuit, also known as an amplitude-stabilized sine-wave oscillator. It provides a high-purity sine wave output. This sine wave oscillator circuit is designed to generate a stable sine wave output with minimal distortion, making it...

This VHF VCO circuit operates within the frequency range of 30 to 200 MHz. Q1 may be substituted with a 2N3563 for frequencies exceeding 100 MHz. The inductor, L1, is selected to resonate at the desired frequency in conjunction...

A 52 MHz third overtone crystal typically has a series resonance impedance of 30 ohms as per manufacturer specifications. The crystals utilized in the prototypes exhibit nearly ten times lower series resistance but are significantly more expensive. An oscillator...
