Abstract
Official abstract text for this publication.
In one embodiment, the present disclosure includes a circuit comprising an amplifier having an input and an output, an offset detection circuit to detect an offset of the amplifier at the output of the amplifier, and an offset generation circuit having an input coupled to the offset detection circuit and an output coupled to the input of the amplifier to generate an offset at the input of the amplifier during an operational phase of the amplifier based on the detected offset. The generated offset cancels a least a portion of the offset of the amplifier. In one implementation, the amplifier is a sense amplifier in a memory.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for determining offset in an amplifier, the method comprising: generating, using offset generation circuitry, an offset value at an input of an amplifier; determining, using offset detection circuitry, whether an output of the amplifier is greater than an output threshold; and setting, using control circuitry, an offset inject value which indicates that an offset should be generated at the input of the amplifier if the output is determined to be…
