Consideration Based on ESD Applied Waveform in High-Speed IF Using T-Coil

Abstract: T-coil circuit is capable of mitigating the influence of parasitic capacitance in ESD protection circuits, but the mutual induced voltage reduces ESD robustness. In this study, HBM, CDM, TLP ...

Zero-sum Thinking and the Roots of US Political Differences

We investigate the origins and implications of zero-sum thinking: the belief that gains for one individual or group tend to come at the cost of others. Using a new survey of 20,400 U.S. residents, we ...

New Power Clamp Circuit for Concurrent ESD and Surge Protections

Abstract: An important development trend of ON-chip power clamp circuits is that they should be able to deal with more types of power rail overstress events, such as electrostatic discharges (ESDs) ...
