Abstract:
A noise-suppression circuit for improving immunity to noise due to cross-coupling between independent first and second single-ended output control lines of a dynamic logic circuit having independent mutually exclusive first and second control signals thereon, said noise-suppression circuit comprising:a first FET having a drain coupled to said first single-ended output control line of said dynamic logic circuit and a gate coupled to said second single-ended output control line of said dynamic logic circuit; and a second FET having a drain coupled to said second single-ended output control line and a gate coupled to said first single-ended output control line; and wherein said first FET actively suppresses high-going pulses on said first single-ended output control line when said first single-ended output control line is low, and said second FET actively suppresses high-going pulses on said second single-ended output control line when said second single-ended output control line is low.
