ABSTRACT:
A frequency divider or dual module prescaler having a division factor switchable between 1/N and 1/(N+1) with an input signal frequency of approximately 1 GHz. The divider includes only one input flip-flop to process the input signal and an intermediate signal having half the frequency as supplied to a divider expansion either directly, or in inverted.
