Abstract

See full text

A circuit includes a counter circuit, a logic circuit, and a clock divider. The counter circuit includes a clock divider counter to be loaded with most significant bits of a divider value, and decremented at a same edge of each pulse of a clock signal. The logic circuit compares a value contained in the divider counter to a reference value and generates an end count signal as a function of the value contained in the divider counter matching the reference value, and transitions a toggle signal at a same edge of each pulse of the end count signal. The clock divider counter is reloaded with the most significant bits of the divider value as a function of the end count signal. The clock divider generates a divided version of the clock signal as a function of the toggle signal.
