Abstract
Official abstract text for this publication.
A driver circuit includes pull-up and pull-down drivers driven by separate pre-drivers operating between different voltage rails. Data signals driving the pull-up driver and the pull-down driver are synchronized, and the pull-up driver and the pull-down driver are coupled together to produce an output signal having a voltage swing based on both the pull-up driver and the pull-down driver.
First claim
Opening claim text (preview).
What is claimed is: 1. A driver circuit comprising: a pull-up driver operating within a first voltage swing range; a pull-down driver operating within a second voltage swing range that is not coterminal with the first voltage swing range, wherein data signals driving the pull-up driver and the pull-down driver are synchronized, and the pull-up driver and the pull-down driver are coupled together to produce an output signal having a voltage swing based on both the pull-up drive…
