Ceramic Resonator Oscillator

Similar to the crystal oscillator ceramic resonator is also an electronic circuit or a device used to generate an output of oscillation frequency with the help of ceramic as a resonating piezoelectric material.

Ceramic resonator oscillator.

Like the similar quartz crystal they are used in oscillators for purposes such as generating the clock signal used to control timing in computers and other digital logic devices or generating the. In a ceramic resonator oscillator the inductor is replaced by a ceramic resonator taking advantage of the fact that the resonator becomes inductive between resonant and anti resonant frequencies. What is a ceramic resonator. Ceramic resonators are made of lead zirconium titanate pzt and are easier to manufacture than crystal oscillators made out of fine cut quartz.

Ceralock find a broad range of applications such as automotive electronics communications personal computing and medical healthcare equipment. The operating principle of these oscillation circuits can be seen in fig 2 1. In terms of application ceramic resonators are used in microprocessors where their frequency stability is not important and crystal oscillators are used for more precise time based applications. On the left the crystal right the ceramic resonator.

Another oscillating circuit is the one that use resonators. The active part which makes the oscillator work is an amplifier which supplies the energy to keep the oscillation going. The most commonly used circuit is the colpitts circuit. The resonator or crystal itself has two connections.

See that tutorial for more information. Before we look at the ceramic and crystal resonators let s take a look at the lc oscillator so we need a coil and capacitor. The most commonly used circuit is the colpitts circuit. When connected in an electronic oscillator circuit resonant mechanical vibrations in the device generate an oscillating signal of a specific frequency.

What is a ceramic resonator. A ceramic resonator is sometimes referred to a dielectic resonator they are commonly used for timing devices which create a clock signal. The operating principle of these oscillation circuits can be seen in fig. Remember from the inductance meter tutorial that an lc tank will resonate at its natural frequency.

A ceramic resonator works similar to a crystal. A ceramic resonator is an electronic component consisting of a piece of a piezoelectric ceramic material with two or more metal electrodes attached. The material can have two or more electrode which when connected to an oscillator circuit gets mechanical vibration as a result an oscillating signal of a specific frequency is generated. In a ceramic resonator oscillator the inductor is replaced by a ceramic resonator taking advantage of the fact that the resonator becomes inductive between resonant and anti resonant frequencies.

Like you say the oscillator needs extra components the two capacitors.
