Abstract

See full text

A counter (200) generates signals which have an average period of a non-integer multiple of an input clock period. Through the use of this non-integer multiple period, non-integer division operations are executed and used in circuits such as pulse width modulators (800) and phase lock loops (900). Additionally, when the counter (200') is used with a Gray coded counter, the average duty cycle of all bits is exactly equal to 50%.
