  • Pulse skew control
    Patent number: 5684424
    Abstract: A pulse generator for use in generating pulses at different locations within a circuit has a first circuit 501 for a time dependent operation after receipt of a first input pulse and a second circuit 502 for carrying out a time dependent operation after receipt of a second input pulse after the first input pulse. A third circuit 503 is responsive to each of the first and second circuits 501,502 reaching respective predetermined conditions so that an output pulse is produced by the third circuit 503 at a time dependent on the average durations of operation of the first and second circuits 501 and 502.
