Asynchronous circuit insensitive to the delay with insertion circuit time limit

摘要

The asynchronous circuit insensitive to the periods comprises at least one circuit for the insertion of time on the path of propagation of a signal. The insertion of the delay circuit comprises, between an input (5) and an output (sd) of the signal, a door by muller (5) and a plurality of delay circuits (d1. dn) connected in series with an output of the door by muller (5). The outputs of the delay circuits are connected to corresponding inputs of a multiplexing circuit (7, 8, 15) having an output constitutes the output of the insertion circuit period. The door by muller (5) comprises an input connected to the output of the last time delay circuit (dn), by means of an inverting gate (6), and an input constituting the input of the signal in the insertion circuit period. The control circuit (8) of multiplexing preferably includes a random generator.
