Programmable low power multi-modulus divider with 50/50 duty cycle
Abstract:
Disclosed is a method and apparatus for a modular high performance low power divider with 50/50 duty cycle output. The modularity offers custom dividers to be quickly developed while maintaining minimum power usage. A multi-modulus divider (MMD) receives an input signal and outputs an MMD output signal. The MMD includes a chain of modulus divider stages in such a way as to generate any divide value from 1 to 2(n+1)−1 (n is the number of cascaded elements) while maintaining a 50/50 duty cycle output. Power can be dramatically reduced as the frequency of each subsequent element is halved. The modular nature allows rapid development of any dividers simply by adding more elements to the chain.
