XLL73V614.400000I Working Principle

XLL73V614.400000I oscillator consists of a single transistor, often a power MOSFET, and two capacitors. The transistor is used as an amplifier/switch, and the capacitors provide the voltage gain to the circuit. The two capacitors work together to form what is known as a ‘charge pump’ or ‘battery discharge’ circuit. One of the capacitors stores and supplies electric charge, while the other forms a ‘residual’ capacitor.

The switch is connected to one of the capacitors, so that when the capacitors reach their peak values, the switch opens and closes the loop, thus allowing the capacitor to charge up and discharge. This process is repeated, thus producing a periodic oscillating signal, and usually a sine wave.

The frequency of the signal generated by the XLL73V614.400000I oscillator is controlled by changing the devices used in the amplifier/switch, and the capacitors which provide the charge and voltage gains. By varying these components, different frequencies of oscillations can be achieved.

In addition to the basic application of XLL73V614.400000I oscillator, multiple stages of amplifiers may be used in order to produce signals with more accurate frequencies. This is usually done for frequency sensitive communication systems.
