APPARATUSES AND METHODS FOR DUTY CYCLE ADJUSTMENTS

摘要

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.

1. 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 a first output node, the first pull-down circuit configured to be controlled responsive to a first control signal, the two adjacent logic gates coupled between a first input node and the first output node; and a second pull-down circuit coupled to a second output node and the first node, the second pull-down circuit configured to be controlled responsive to a second control signal.
