Abstract
An apparatus comprising a frequency divider comprising a first latch configured to receive a first clock signal and a complement of the first clock signal and to generate a first latch first output, and a second latch coupled to the first latch in a toggle-flop configuration, a first output circuit comprising a p-channel transistor, wherein the gate of a p-channel transistor is configured to receive the first clock signal, and a n-channel transistor, wherein the drain of the p-channel transistor is directly connected to the drain of a n-channel transistor, wherein the gate of the n-channel transistor is configured to receive the first latch first output, wherein the source of the n-channel transistor is configured to receive the complement of the first clock signal, and wherein the first output circuit is configured to generate an in-phase reference signal, and a second output circuit configured to generate a quadrature signal.
