Abstract: Some embodiments relate to a sense amplifier output buffer configured to buffer an output of a sense amplifier. The sense amplifier output buffer includes a first pull-up element having a source coupled to a first DC supply terminal and having a drain coupled to an output terminal of the sense amplifier output buffer. A first pull-down element is in series with the first pull-up element and has a source coupled to a second DC supply terminal and has a drain coupled to the output terminal. A miller capacitance decoupling circuit is coupled between the drain of the first pull-up element and the drain of the first pull-down element. The miller capacitance decoupling circuit is configured to decouple miller capacitance associated with the drains of the pull-up and pull-down elements from the output terminal. Other embodiments are also disclosed.
