Oscillators

Oscillators are electronic circuits that produce a periodic fluctuation in voltage, usually between two states of a predetermined value. The oscillations can be generated either from a digital logic circuit consuming electrical energy from a power source (such as a battery) or an AC signal produced by an external time-varying voltage source such as a function generator. Oscillators can be divided into two main categories–analog and digital.

SIT1602AI-13-18E-75.000000D application field and working principle

SIT1602AI-13-18E-75.000000D is a type of analog oscillator. It is made of a linear integrated circuit, and its operating frequency is determined by an external resistor and capacitor. The operating frequency and stability of the oscillator are related to the temperature, humidity and aging of the resistor and capacitor. This oscillator can be widely used in many fields, such as portable telephones, CD players, cameras, microwaves, automobiles and other portable electronic devices. Its working principles are as follows:The SIT1602AI-13-18E-75.000000D oscillator consists of an oscillator circuit, a feedback loop, and a wave generator. The oscillator circuit uses a bipolar transistor (Q1) and a pair of transistors (Q2 and Q3) as active elements. The feedback loop consists of a capacitor C1 and a resistor R1 connected between the emitter and collector of Q1. Finally, the wave generator consists of a capacitor C2 connected to the base of Q1 and a resistor R2 connected to the emitter of Q2.When the oscillator is powered up, a base current flows into the base of Q1, and a collector voltage is generated across R2. The collector voltage is then fed back to the base of Q1 through the feedback loop, and a negative voltage is developed across C1 and R1. This in turn serves to reduce the base current of Q1, thus stabilizing the oscillator’s frequency.The waveform of the oscillator is determined by the values of R2, C1 and C2. Together with the biasing voltage provided by R1, they form an RC network that produces a sinusoidal waveform.In conclusion, the SIT1602AI-13-18E-75.000000D oscillator is a type of analog oscillator that can be used for various applications. It is composed of a linear integrated circuit and operates with an external resistor and capacitor. It produces a sinusoidal waveform, which is determined by the values of the external resistor, capacitor and biasing voltage.
