Abstract
Systems and methods for producing a frequency divider output signal having a period substantially equal to three times a period of a reference input signal, comprising configuring each of three storage elements to receive a first input, a second input, and a reference input signal, and to provide a storage element output, obtaining a frequency divider output signal from at least one storage element output, and using the storage element output from each of the three storage elements as an input to another one of the three storage elements, where a phase difference between the output of the first storage element and the output of the second storage element is substantially equal to 60°.
Claims18
A signal processing system configured to produce a divider output signal having a period substantially equal to three times a period of a reference input signal, the signal processing system comprising:
- a first storage element;
- a second storage element;
- and
- a third storage element,
- where each of the three storage elements is configured to receive a first input, a second input, and a reference input signal, and is configured to provide a storage element output and a frequency of each output of the three storage elements has a frequency equal to one third of a frequency of the reference input signal,
- where the divider output signal is obtained from at least one storage element output, and where the divider output signal is obtained by combining only two of the three storage element outputs by adding or summing the two storage element outputs together, and
- where the storage element output from each of the three storage elements is used to provide at least one input to another one of the three storage elements, where a phase difference between the output of the first storage element and the output of the second storage element is substantially equal to 60°.
