Introduction to Oscillators

Oscillators are electronic circuits used to generate a steady waveforms (usually sine, square, or sawtooth) of a desired frequency. As the name suggests, an oscillator produces oscillations or vibrations in an alternating voltage. Oscillators are extremely important in electronics and provide the basis of modern communication, radio and television, computers, and virtually all other electrical and electronic technologies.

ASEMPC-20.000MHZ-Z-T Oscillator

The ASEMPC-20.000MHZ-Z-T Oscillator is an oscillator designed to generate a steady sine waveform at a desired frequency of 20 MHz. This type of oscillator utilizes a commonly used Pierce circuit configuration, a design developed by Professor Claude Elwood Shannon at Bell Laboratories in the 1950s. The Pierce circuit utilizes an amplifier, a tuned circuit consisting of an inductor-capacitor (LC) tank circuit, and an op-amp to provide the necessary positive and negative feedback signals.

Application Field and Working Principle

The ASEMPC-20.000MHZ-Z-T Oscillator is used in a variety of applications, including high-frequency radio transmission and signal processing, clock generation, and in the design of frequency synthesizers. It is also used in medical imaging, ultrasound imaging, and other applications requiring precise frequency control.

The working principle of the ASEMPC-20.000MHZ-Z-T Oscillator is based on the positive feedback concept. The LC tank circuit, consisting of an inductor and capacitor, is tuned to the desired frequency. The op-amp amplifies the signal and sends it back to the input of the tank circuit. The amplifier and the tuned circuit then act as a resonator, continually exchanging energy until the signal is stabilized and an oscillation is obtained. The magnitude of the oscillations can be controlled by adjusting the gain of the amplifier.

Conclusion

The ASEMPC-20.000MHZ-Z-T Oscillator is a precision, high frequency device designed to provide a steady sine waveform at 20 MHz. This type of oscillator utilizes a Pierce circuit configuration and utilizes positive feedback to achieve stabilization. It is used in a variety of applications requiring precise frequency control including high-frequency radio transmission and signal processing, clock generation, and frequency synthesis.
