What Is a Ceramic Resonator?
A ceramic resonator is an electronic component that utilizes the mechanical resonance of a polycrystalline material called piezoelectric ceramics (lead zirconate titanate, called PZT, is the most common). They are utilized in various situations depending on the oscillator's resonant frequency.
Traditionally, quartz crystal has often been used as the material for such oscillators. Both of these two types of oscillators do not require adjustment, and quartz is superior in terms of long-term stability, but it has the disadvantages of being expensive and having a large shape. However, they have the disadvantages of being expensive and large in size. Ceramic resonators, which are inexpensive and small in size, have recently come into use.
Applications of Ceramic Resonators
Products such as smartwatches, smart rings, and hearable devices that people wear are required to be compact and lightweight so that they can be worn for long periods of time with little burden on the wearer. To meet this requirement, compact and lightweight ceramic resonators are used.
These resonators are used as timing circuits in an extremely wide range of fields and products, including PC-related equipment, automotive electrical components, TVs, videos, cameras, electrical equipment, copy machines, remote controls, and toys.
Principle of Ceramic Resonators
The oscillation circuit of a ceramic resonator can be divided into three types. The first is a positive feedback type, the second uses a negative resistive element, and the third uses a phase delay/transfer time. The first type is used not only in ceramic resonators but also in quartz crystal units and LC circuits. The advantages and features of ceramic resonators are briefly introduced here.
1. Relatively Stable Oscillation Frequency
Stability is about halfway between that of quartz crystal units and LC or CR oscillation circuits and is relatively high.
2. Light Weight, Small Size, and Low Price
The size is less than half that of a quartz crystal unit. It is also designed for mass production, making it less expensive than other types of crystal units.
3. No Adjustment of the Oscillation Circuit
Since it is highly resistant to the effects of external circuits and power supply voltage fluctuations, there is no need to adjust the circuit, and a very stable oscillation circuit can be obtained.
One demerit of ceramic resonators is that their frequency accuracy is inferior to that of crystals. Therefore, it should be used in circuits where strict accuracy is not required.
Characteristics of Ceramic Resonators
Ceramic resonators are oscillation devices that utilize the mechanical resonance of piezoelectric ceramics. As various digital circuits (including computers) are built into industrial and consumer equipment, toys, motorcycles, and automobiles, the internal reference clocks of individual devices are becoming increasingly important, and the interrelationship of clocks with each other is also becoming important in synchronizing the various devices. In addition, the interrelationship of clocks between devices has become important for synchronizing each other.
Generally, oscillator circuits can be classified into four categories according to the type of oscillator element.
- LC transmitter circuit: Inexpensive but large in size, requires adjustment, and is not stable. Initial frequency accuracy is about ±2%.
- CR transmitter circuit: Inexpensive and small in size. Adjustment is required, and stability is not good. Initial frequency accuracy is about ±2%.
- Crystal oscillation circuit: Expensive and relatively large in size. No adjustment is required, and excellent stability. Initial frequency accuracy is about ±0.001%.
- Ceramic oscillation circuit: Inexpensive and small in size. No adjustment is required. Stable but inferior to crystal oscillators. Initial frequency accuracy is about ±0.5%.
As described above, ceramic oscillator circuits can generate a relatively high-precision and stable reference signal without incurring high costs.
Generally, the required reference clock accuracy for devices such as 1-chip microcontrollers is a few percent, making ceramic oscillators sufficiently practical. An oscillation circuit that can be realized without adjustment is a great advantage and is used in many devices such as toys and remote controls.
