Abstract: A frequency divider is provided that includes a plurality of latches for dividing an input clock according to an integer frequency divisor N of three or greater. Each latch is coupled to a corresponding pair of logic gates. For each latch, one of the logic gates in the corresponding pair controls a setting of the latch whereas a remaining one of the logic gates in the corresponding pair controls a resetting of the latch. Each latch outputs a pair of overlapping clock signals that are divided in frequency with respect to the input clock and have a 50% duty cycle. Each logic gate processes a pair of the overlapping clock signal and the input clock signal to provide a non-overlapping clock signal of the same frequency of the overlapping clock signals but have a (50/N) % duty cycle.
