BACC63CB14-3SN Application Field and Working Principle

The BACC63CB14-3SN is an integrated circuit that finds application in the field of analog circuitry. It is typically used in electronic communication systems such as telephones, computers and traffic control systems. The circuit mainly contains two sections: an oscillator and a multiplier stage.

Oscillator Stage

The oscillator stage of the circuit contains four transistors. The working of the stage is based on the principle of Negative Resistance (NR). In this, a negative voltage is applied to the input of the stage. This voltage causes current to flow through the circuit in comparison to a normal positive voltage. As a result, the current gain in the transistor increases due to its modified input voltage. Thus, it creates an oscillating output at the collector of the transistor. By properly controlling the biasing of the transistor\'s base, collector and emitter nodes, an oscillation can be generated at a desired frequency.

Multiplying Stage

The multiplying stage of the circuit contains two transistors and two capacitors connected in between the transistors. In this stage, the input signal is multiplied using the capacitive feedback. When a signal is applied at the input of the stage, it is first amplified by the first transistor followed by capacitive feedback. This phenomenon of capacitive feedback causes the output voltage to inversely proportional to the input voltage. As a result, the input signal is multiplied by the second transistor and thereby increases the overall gain of the circuit.

Conclusion

The BACC63CB14-3SN integrated circuit finds applications in various analog circuitry systems. It has two sections which are the oscillator stage and the multiplier stage. The working of the oscillator stage is based on the principle of Negative Resistance. The working of the multiplier stage is based on the principle of capacitive feedback.
