Abstract:A novel 600 V high-voltage IC (HVIC) featuring a high noise tolerance is proposed. The purpose of the proposed HVIC is to achieve the high noise tolerance without an increase of the fabrication cost. The basic device concept is to arrange a P− separation layer around the high-side control part, which is called a new self-shielding structure, to reduce a hole current injection under the condition of negative transient voltage noise. By applying the new self-shielding structure in the HVIC, more than 3× higher n… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
