ABSTRACT
Considering oscillator circuits are implemented in almost every electronic product today, these fundamental circuits can be thought of as the foundation for many devices. Oscillator circuits provide clean and dependable signals to drive other devices, so as to provide a reference or clock signal in the form of a square wave, triangle wave, or sine wave. For example, oscillators are used to operate key functionality in metal detectors, radios, and stun guns.
In order to design a collector-coupled BJT oscillator, also known as a relaxation oscillator, a sufficient amount of calculation and simulation time is required. Using PSpice to simulate the collector-coupled BJT oscillator, transient analysis and frequency response curves can be used to determine key signal parameters, such as amplitude, frequency, total harmonic distortion (THD), and DC offset voltage. After simulation, practical implementation can be used to attain these same parameters to determine the......
