Abstract
A signal generation circuit generates first and second non-overlapping digital signals from an input pulse signal. A first digital circuit includes: a first logical OR gate receiving the second digital signal and the input pulse signal to generate a third digital signal; and a second logical OR gate receiving the input pulse signal and a delayed version of the third digital signal to generate the first digital signal. A second digital circuit includes: a first logical AND gate receiving the first digital signal and the input pulse signal to generate a fourth digital signal; and a second logical AND gate receiving the input pulse signal and the fourth digital signal to generate the second digital signal.
Claims24
A circuit including a signal generation circuit configured to generate a first digital signal and a second digital signal from an input pulse signal, wherein the first and second digital signals are non-overlapping, the signal generation circuit comprising:
- a first digital circuit comprising:
- a first logical combination of the second digital signal and the input pulse signal to generate a third digital signal;
- and
- a second logical combination of the input pulse signal and the third digital signal to generate the first digital signal;
- a second digital circuit comprising:
- a third logical combination of the first digital signal and the input pulse signal to generate a fourth digital signal;
- and
- a fourth logical combination of the input pulse signal and the fourth digital signal to generate the second digital signal.
A circuit, comprising:
- a first terminal configured to receive an input pulse signal;
- a first OR-type logic function having a first input coupled to the first terminal and having an output coupled to a second terminal configured to supply a first digital signal;
- a first AND-type logic function having a first input coupled to the first terminal and having an output coupled to a third terminal configured to supply a second digital signal;
- a second AND-type logic function having a first input coupled to the first terminal, having a second input coupled to the second terminal, and having an output coupled, via a first delay element, to a second input of the first AND-type logic function;
- and
- a second OR-type logic function having a first input coupled to the first terminal, having a second input coupled to the third terminal and having an output coupled, via a second delay element, to a second input of the first OR-type logic function.
A circuit including a signal generation circuit configured to generate a first digital signal and a second digital signal from an input pulse signal, wherein the first and second digital signals are non-overlapping, the signal generation circuit comprising:
- a first logic OR-type function configured to supply the first digital signal in response to the input pulse signal and delayed information from a first logical combination of the second digital signal and the input pulse signal;
- and
- a first logic AND-type function configured to supply the second digital signal in response to the input pulse signal and delayed information from a second logical combination of the first digital signal and the input pulse signal.
