Abstract
A frequency divider may be provided. The frequency divider may be configured to generate a division signal having a variable cycle according to transition timing information and a division ratio signal.
Claims20
A frequency divider comprising:
- a timing information generation circuit configured to generate transition timing information of an input signal;
- a control circuit configured to generate an output control signal according to the transition timing information and a division ratio signal;
- and
- a division signal generation circuit configured to generate a division signal having a variable cycle according to the output control signal.

A frequency divider comprising:
- a timing information generation circuit configured to generate a transition timing signal according to an edge of an input signal;
- a division ratio signal generation circuit configured to generate a division ratio signal based on an external control signal;
- a control circuit configured to compare the division ratio signal to a count signal generated by counting the transition timing signal, and generate an output control signal;
- and
- a division signal generation circuit configured to generate a division signal having a variable cycle according to the output control signal.
