Abstract
Official abstract text for this publication.
This disclosure provides systems, methods, and apparatus for providing a cascode driver circuit for providing positive and negative polarities of two or more voltages at an output node. The voltages provided by the cascode driver circuit can be used to provide voltages to various interconnects and terminals of the display apparatus. The cascode driver circuit includes a first circuit for providing a positive polarity of two or more voltages to an output node via a first set of cascode transistors and a second circuit for providing negative polarities of the two or more voltages via a second set of cascode transistors. The driver circuit includes body-effect mitigation circuitry for reducing the impact of body-effect on the performance of the driver circuit. The driver circuit also includes circuitry for reducing substrate leakage current.
First claim
Opening claim text (preview).
What is claimed is: 1. An apparatus comprising: an output node; and a driver circuit coupled to the output node including: a first circuit, including a first set of cascode transistors, capable of selectively providing at least two voltage levels with a first polarity to the output node via the first set of cascode transistors, and a second circuit, including a second set of cascode transistors, capable of selectively providing a second polarity, opposite to the first polarit…
