摘要： A dynamic frequency divider is proposed in which a double mixer is used for the dynamic frequency division. In one example the division is by N, where N≧2 and a positive integer. The dynamic frequency divider further includes an input stage with level shift means, a filter filtering the output signal and providing a feedback signal to the double mixer. In one case, using just one double mixer significantly reduces the power consumption of a dynamic frequency divider and utilizes considerably less space, making it simpler, cheaper and smaller.
