Abstract
The quadrature divider comprises a plurality of flip-flops, including at least a first flip flop and an endmost flip-flop, interoperably coupled in series to produce a predetermined dividing ratio, wherein each of the plurality of flip-flops includes differential inputs, differential outputs and differential clock inputs, the outputs of one flip-flop are connected to the corresponding inputs of a subsequent flip-flop, the outputs of the endmost flip-flop are connected inversely to the inputs of the first flip-flop, wherein the flip-flops are clocked at their clock inputs with differential clock signals in a consecutive manner which, for each flip-flop and depending on the dividing ratio, are individually selected from quadrature clock input signals.
