Introduction to Oscillators

Oscillators, whether electrical, mechanical, acoustic, or optical, involve the oscillatory motion of a system from which some amount of energy is derived to maintain the system’s motion. Electric oscillators, the most common type, produce an alternating current at a specific frequency. In many applications, oscillators play an important role in transmitting and receiving signals and in generating the stable timing of electronic systems.

Types of Oscillators

An oscillator can be classified based on the configuration used to generate the waveforms. Common types of oscillators are classified as harmonic oscillators, relaxation oscillators, and linear oscillators. Harmonic oscillators, also called linear oscillators, are those in which the damping force is proportional to the displacement of the system, thus resulting in sinusoidal oscillations. An example of a harmonic oscillator is a simple pendulum, driven by energy from gravity, and oscillating in an ellipse-shaped pendulum. Relaxation oscillators, also known as aperiodic or non-sinusoidal oscillators, do not produce perfectly sinusoidal output voltages. Instead, these oscillators produce waves of a particular shape, such as a square wave or a triangle wave. The waveforms produced by relaxation oscillators are produced by a combination of frequency modulation and amplitude modulation. Linear oscillators are those that are characterized by a linear transfer function. Linear oscillators are usually classified according to the type of energy source that drives the oscillations, which can be either a DC, or alternating current (AC). examples of linear oscillators include the Van der Pol and forced-harmonic oscillators.

AX7MAF1-2000.0000T Application Field and Working Principle

The AX7MAF1-2000.0000T oscillator is a type of relaxation oscillator designed for use in pulse-width modulation systems. The oscillator consists of a resistor and capacitor in series with each other, and a transistor connected in parallel to these components. When powered with a supply voltage, the transistor will operate as an emitter follower, providing bias to the resistor, resulting in a varying voltage across the resistor and capacitor. This variation in voltage is used to cause a changing current in the transistor, which causes the transistor to act as a voltage amplifier. The output from the transistor is then connected to the input of a pulse-width modulator, which converts the signal into a pulse-width modulation signal. The carrier frequency of the signal is determined by the resistor and capacitor values. When the frequency of the signal is reduced, the pulse width of the modulation signal is also decreased. The oscillator is primarily used in application such as controlling the speed of a DC motor, as well as providing pulse-width modulation signals for various applications. The main advantages of this type of oscillator are its low cost, low power consumption, high frequency stability, and low distortion.

Conclusion

In conclusion, the AX7MAF1-2000.0000T oscillator is a versatile and reliable relaxation oscillator designed for use in pulse-width modulated applications. The oscillator’s main advantages include its low cost, low power consumption, high frequency stability and low distortion. It is ideal for applications such as controlling the speed of a DC motor and providing pulse-width modulation signals for various applications.
