Design A Clock Divide By 3 Circuit. CircuitLab provides online in-browser tools for schematic capture and circuit simulation. Design a clock divide-by-3 circuit with 50 duty cycle. Blanket Junior Member level 3. Typical divide by 3 circuits will either.
The idea now is to use the falling edge of the clock to sample one of the counter bits and generate simply a delayed version of it. Building circuits with higher level elements generally speeds the design process and simplifies troubleshooting. After the first stage the frequency became frac100MHz2 50 MHz. We started working at the following verilog code to implement the divide by 3. Sometimes this approach is used to generate a clock with 50 duty cycle even starting from a source clock that has a duty cycle. Dec 30 2005 18 B.
After the second stage the frequency became frac100MHz22 25 MHz.
Typical divide by 3 circuits will either. Frequency or clock dividers are among the most common circuits used in digital systems. Suppose that the input clock frequency to the first stage is 100 MHz 1000000Hz. Use positive and negative edges and have a 50 duty cycle if the input is 50. Designing such a circuit where N is a non-integer is not as difficult as it seems. The trick is how to come up with a minimal design implementing as little as possible flip-flops logic and guaranteeing glitch free.
