Abstract
A signal width repair circuit and method, and an electronic device are provided. The signal width repair circuit includes: a delay unit, configured to receive an input signal, and delay the input signal for a preset duration to obtain a delayed signal, the input signal being a low-level signal; a signal reconstruction unit, configured to receive the input signal and the delayed signal, and repair the input signal and the delayed signal to obtain a repaired signal; and a signal selection unit, configured to receive the input signal and the repaired signal and select one of the input signal and the repaired signal for output, to obtain a target signal that has a width satisfying a preset width, the preset duration being equal to or greater than a duration with the preset width.
Claims20
A signal width repair circuit, comprising:
- a delay circuit, configured to receive an input signal, and delay the input signal for a preset duration to obtain a delayed signal, the input signal being a low-level signal;
- a signal reconstruction circuit, configured to receive the input signal and the delayed signal, and repair the input signal and the delayed signal to obtain a repaired signal;
- and
- a signal selection circuit, configured to receive the input signal and the repaired signal, and select one of the input signal and the repaired signal for output, to obtain a target signal that has a width satisfying a preset width, wherein the preset duration is equal to or greater than a duration with the preset width.
A signal width repair method, applied to a signal width repair circuit comprising a delay circuit, a signal reconstruction circuit and a signal selection circuit, the signal width repair method comprising:
- controlling the delay circuit to receive an input signal, and delaying, by the delay circuit, the input signal for a preset duration to obtain a delayed signal, the input signal being a low-level signal;
- controlling the signal reconstruction circuit to receive the input signal and the delayed signal, and repairing, by the signal reconstruction circuit, the input signal and the delayed signal to obtain a repaired signal;
- and
- controlling the signal selection circuit to receive the input signal and the repaired signal, and selecting, by the signal selection circuit, one of the input signal and the repaired signal for output, to obtain a target signal that has a width satisfying a preset width, wherein the preset duration is equal to or greater than a duration with the preset width.
An electronic device, comprising a signal width repair circuit, wherein the signal width repair circuit comprises:
- a delay circuit, configured to receive an input signal, and delay the input signal for a preset duration to obtain a delayed signal, the input signal being a low-level signal;
- a signal reconstruction circuit, configured to receive the input signal and the delayed signal, and repair the input signal and the delayed signal to obtain a repaired signal;
- and
- a signal selection circuit, configured to receive the input signal and the repaired signal, and select one of the input signal and the repaired signal for output, to obtain a target signal that has a width satisfying a preset width, wherein the preset duration is equal to or greater than a duration with the preset width.
