ABSTRACT:
A duty cycle bounding circuit for restoring the unbounded duty cycle of a periodic signal such as a forwarded clock signal. The duty cycle bounding circuit comprises a state holding logic element, such as a C-element, and a delay line. The delay line feeds back an inverted version of the output of the state holding logic element to an input of the state holding logic element. The periodic signal is applied to another input of the state holding logic element.
