Very-low-duty-cycle-pulse-generator
A precise pulse generator can be constructed using a precision oscillator and several CMOS counters. The number of counters can be increased to extend the pulse period as needed. This circuit will generate a pulse approximately 5 ms long every 24 hours, resulting in a duty cycle of about 5.9-6%.
The pulse generator circuit utilizes a precision oscillator, which serves as the primary timing source. The oscillator produces a stable frequency output that drives the CMOS counters. Each counter in the circuit divides the input frequency by a predetermined factor, allowing for the adjustment of the pulse period. By cascading multiple counters, the overall division ratio can be increased, thereby extending the duration of the output pulse.
In this specific implementation, the design aims to create a pulse with a duration of 5 ms occurring once every 24 hours. This is achieved by appropriately configuring the counters to divide the oscillator frequency down to the desired interval. The output pulse's duty cycle is a critical parameter, which in this case is maintained at approximately 5.9-6%. This means that the pulse is active for only a small fraction of the total period, making the circuit suitable for applications requiring low power consumption and minimal heat generation.
To ensure accuracy and stability, the precision oscillator may be implemented using a crystal oscillator or a similar high-stability timing device. The choice of CMOS counters is also significant, as they provide low power operation and high noise immunity, which is essential for maintaining the integrity of the pulse output over extended periods.
Overall, this pulse generator circuit can be widely used in applications such as timekeeping, low-frequency signaling, and other scenarios where precise timing and low duty cycles are necessary. The modular design allows for flexibility in adjusting the pulse duration and frequency, catering to various requirements in electronic systems.Using a precision oscillator and a few CMOS counters, you can build a precise, very low dutycycle pulse generator. You can add as many counters as you desire to make the period as long as you wish. The circuit will generate a pulse about 5 ms long every 24 hours-one 5. 9 -6% duty cycle. 🔗 External reference
