ABSTRACT:
A transition detector circuit comprises a first invertor train comprising 2n stages of invertors (n: positive integer including zero), the input thereof being connected to a signal input terminal while the output thereof is connected to an in-phase output terminal, a second invertor train comprising 2n+1 stages of invertors, the input thereof being connected to the signal input terminal, while the output thereof is connected to an antiphase output terminal, a third invertor train comprising at least one stage of an invertor, which is connected to the output of the first invertor train, a fourth invertor train, comprising at least one stage of an invertor, which is connected to the output of the second invertor train, and a fifth invertor train comprising at least one stage of an invertor, which is connected to the signal input terminal. The transition detector circuit further comprises a first switching circuit which turns on or off in response to a signal fed from the third invertor train to produce a pulse signal having a first delay time determined by the first and third invertor trains, and a second switching circuit which turns on or off in response to a signal fed from the fourth invertor train and turns off or on in response to a signal fed from the fifth invertor train to produce a pulse signal having a second delay time determined by the second, fourth and fifth invertor trains.
