Abstract:
1. An oscillating ring circuit, comprising: a plurality of non-inverting five state dual domino driving stages, each comprising an N-dynamic stage and a P-dynamic stage complementary thereto and having a signal input, an N-trigger input, a P-trigger input, a precharge state clock, a pre-discharge state clock, an N-cutoff clock, a P-cutoff clock and an output inverter; and a plurality of non-inverting stages, each comprising a number of said non-inverting five state dual domino driving stages coupled to form a chain wherein a first non-inverting stage of the chain receives a logic signal input, a single N-trigger input and a P-trigger input for said chain, wherein an output of each non-inverting stage is a signal input of a next non-inverting stage in said chain, wherein said plurality of said non-inverting stages is configured as a non-inverting dual domino ring wherein an output of each non-inverting stage of said plurality of non-inverting stages comprises an input signal to a next non-inverting stage of said plurality of non-inverting stages and is further fed back to clock an earlier non-inverting stage to allow oscillation in said non-inverting dual domino ring.
