APPARATUSES AND METHODS FOR ADJUSTING TIMING OF SIGNALS

摘要

Apparatuses and methods for adjusting timing of signals are described herein. An example method may include providing an output clock signal responsive to an input clock signal, and adjusting a slew rate of the output clock signal by a delayed output clock signal.

1. An apparatus comprising:
a first inverter configured to receive an input signal and provide an output signal; a first circuit node being substantially floating; a second inverter including an input node coupled to an output node of the first inverter and an output node coupled to the first circuit node; a third inverter including an input node coupled to the first circuit node and an output node coupled to the output node of the fist inverter, the third inverter being configured to change drive strength thereof responsive to bias information; a duty cyck detector confimired to detect a duty cycle of the first output signal and produce duty cycle information; and a bias generator configured to generate the bias information responsive to the duty cycle information.
