Abstract

Oscillators deliver an essentially sinusoidal output waveform without input excitation. They are used in a wide range of applications including testing, communication systems and computer systems. Frequencies range from about 10−3 Hz to 1010手机体育投注平台 Hz, and in many applications a low distortion is required. There are two main classes of oscillators; RC oscillators in which the frequency determining elements are resistors and capacitors and LC oscillators in which the frequency-determining elements are inductors and capacitors. RC oscillators operate from very low frequencies up to about 10 MHz, making them very useful for audio frequency applications, while LC oscillators are useful for frequencies above about 100 kHz, and they are usually used in communications applications. This chapter explores the basic principles governing this class of circuits. The conditions required for oscillation are investigated and frequency and amplitude stability studied. At the end of the chapter, the student will be able to:
