Oscillators

Oscillators refer to electronic components maintaining a stable frequency output through an oscillating circuit. It usually consists of a circuit with two or more electrical components that produces an electrical signal to power other components. With the development of modern electronic technology, oscillators play a more and more important role in communication, positioning, navigation and signal persistence.

The working principle of SIT3907AC-22-33NY-27.000000Y is based on negative resistance and positive capacitance. It consists of an amplifier with a negative resistance and a capacitive feedback loop. When a voltage signal is applied to the amplifier, it will generate a current to flow through the capacitor elements in the feedback loop. During this process, the current flow will form an alternating current in the feedback loop, thus creating the oscillation effect. In steady state, the oscillating frequency is determined by the RC time constant of the feedback circuit. The voltage signal that is applied to the amplifier can be used to regulate the oscillating frequency.
