Multivibrators are a category of electronic circuits which are used to generate an alternating output signal. They are two-state, regenerative devices which switch between two levels of power output and have the ability to control the frequency and the resolution of the output signal. The CD4098BM is a type of multivibrator specifically designed for use in logic applications. In this article, we will look at the application fields and the working principle of the CD4098BM.

Application Fields

The CD4098BM is primarily used in logic and pulse-width modulation (PWM) applications. It is particularly well-suited for applications where a low-power, low-cost solution is required. Examples of this include motor control, clock-frequency generators, piezo-electric transducer drivers, and power control circuits.

In terms of motor control, the CD4098BM can be used to generate the high-frequency signals necessary to control DC motors. It can also generate PWM signals of varying durations, allowing the speed of the motor to be precisely adjusted. In addition, the CD4098BM can also be used to generate sawtooth and triangular waveforms which can be used to synchronize timing across multiple motors.

The CD4098BM can also be used in piezo-electric transducer drivers. This is because the multivibrator is able to generate the high-frequency pulses necessary to drive those transducers. This is particularly useful for applications such as horns, buzzers, and alarms where an alternating sound is required.

Finally, the CD4098BM can be used in power control circuits. This is because it can generate variable-length pulses of varying resolution, allowing for precise control of the output voltage. This is useful for applications such as dimmers, solenoids, and relays where a variable amount of power is needed at any given time.

Working Principle

The CD4098BM is a type of multivibrator specifically designed for use in logic applications. It is a two-state device which oscillates between two levels of power output and can be used to generate a wide range of different output signals. The multivibrator consists of two cross-coupled transistors, an inverter, an oscillator, and an output stage.

At low frequencies, the two transistors are in the cutoff state. This causes the inverter to switch between its two states, producing a pulse at the output and causing the multivibrator to oscillate. At higher frequencies, the two transistors become active and the oscillator generates pulses at a frequency determined by the RC time constant of the circuit. The output stage then amplifies the signal and generates the output signal.

The CD4098BM can be used to generate a wide range of output signals, allowing it to be used in a variety of different applications. It is able to generate a continuous output signal, a pulse-width modulated signal, a sawtooth wave, a triangular wave, and a saw-triangle hybrid wave. It can also be used to generate clock-frequency signals and to control the speed of DC motors.

Conclusion

The CD4098BM is a type of multivibrator specifically designed for use in logic applications. It is a two-state device which oscillates between two levels of power output and can be used to generate a wide range of different output signals. It is most commonly used in motor control, clock-frequency generator, piezo-electric transducer drivers, and power control circuits. The working principle of the CD4098BM involves two transistors, an inverter, an oscillator, and an output stage.
