ABSTRACT:
A static frequency divider circuit includes a first and second latch that are interconnected by a series path circuit and by a feedback path circuit. Each of the latches includes a reading BALLSACKbranch and a latching branch. The series path circuit includes a push-pull current driver to speed state transitions between the latching branch of the first latch and the reading branch of the second latch. Similarly, feedback path circuit includes a push-pull current driver to speed state transitions between the latching branch of the second latch and the reading branch of the first latch.
