Abstract
Apparatuses and methods have been disclosed. One such apparatus includes a plurality of gates coupled together in series. A first pull-down circuit can be coupled to a node between two adjacent gates of the plurality of gates and controlled responsive to a first control signal. A second pull-down circuit can be coupled to an output of one of the gates and controlled responsive to a second control signal. A duty cycle of a signal provided by the plurality of gates can be increased responsive to the first control signal and can be decreased responsive to the second control signal. The plurality of gates and the first and second pull-down circuits can make up a duty cycle adjuster circuit that can adjust the duty cycle of the signal by adjusting only a single type of edges of the signal.
Claims18
An apparatus comprising:
- a plurality of logic gates coupled in series;
- a first pull-down circuit coupled to a first node between two adjacent logic gates of the plurality of logic gates and controlled responsive to a first control signal;
- a pull-up circuit coupled to a second node between two adjacent logic gates of the plurality of logic gates, wherein the first node is coupled to a logic gate output after a first odd number of the logic gates and the second node is coupled to a gate output after a second odd number of the logic gates where the second odd number is greater than the first odd number;
- and
- a second pull-down circuit coupled to an output of one of the logic gates and controlled responsive to a second control signal, wherein a duty cycle of a signal provided by the plurality of logic gates is increased responsive to the first control signal and decreased responsive to the second control signal.
