Abstract
The ring counter of this invention is self-initializing and is operable at a clock frequency corresponding to four gate delays and comprises a plurality of master of slave flip-flops, in which this high speed capability is attained by using non-inverting feedback between the first and last flip-flops and by operating the master and slave of each in complementary fashion without requiring the use of a complementary clock signal. The non-inverting feedback takes advantage of the inherent delay between the response of the complementary outputs of each flip-flop.
