Oscillators are used in many fields of electronic engineering. From the simplest digital clocks and binary number generators to the most complex communication systems, oscillators are necessary components. CE3291-44.736 is one type of oscillator that is used in many applications and its working principle can be divided into two parts, namely structure and circuit.

Structure

CE3291-44.736 consists of several key parts which are four paralleled FETS, resistors, capacitors, transistors and an inductor. As the four FETS are paralleled, when the voltage passing through the FET is changed, the other three FETS will also change in the same way, thus maintaining the output signals\' stability. Especially, the FETs are designed to be short-circuited for an improved oscillation. Besides that, it also comes with a built-in temperature sensor that helps the structure of oscillator more stable in all conditions -- regardless of the temperature.

Circuit

The circuit principle of CE3291-44.736 is simple enough. The output signal of oscillator will come from the four FETS which have been paralleled. These FETS are driven by the oscillator circuit and powered by an external power source. In this circuit system, resistors and capacitors will be connected to the FETS to make sure the oscillation frequency is stable. Transistors and an inductor are also connected to the circuit in order to prevent the circuit from saturating. Furthermore, the temperature sensor will exert its effect to help keep the output signal in the predetermined amplitude range.

Application field and Working principle

The main application of CE3291-44.736 is the frequency-controlled oscillators in various electronic devices such as time pieces, telecommunication, computers, and surveying equipment. The structure of CE3291-44.736 gives it a greater stability in extreme temperatures. This oscillator produces a constant amplitude output signal while the frequency can be varied within a predetermined range. The oscillation rate of this oscillator is determined by external resistors and capacitors which allow engineers to customize the output frequency within certain limits. Furthermore, temperature sensor embedded in structure helps to control the oscillation frequency in a specific temperature range. In summary, CE3291-44.736 has a simple circuit principle , is easy to be tuned and also provides accurate and stable output frequency.
