Title: The Innovations of James S. Hsue
Introduction
James S. Hsue is a notable inventor based in San Francisco, CA. He has made significant contributions to the field of semiconductor technology, holding 2 patents that showcase his innovative approach to electronic design.
Latest Patents
His latest patents include a "Digital output buffer and method with slew rate control and reduced crowbar current." This invention features a buffer characterized by a pull-up network and a pull-down network, both coupled between an input and an output. Each network includes several switch elements that can be sequentially activated or deactivated through an RC network, providing effective slew-rate control. The design incorporates diode bypass networks to minimize crowbar current, allowing both networks to turn on slowly while turning off quickly.
Another significant patent is "Semiconductor FET structures with slew-rate control." This patent implements slew-rate control in input/output device structures utilizing MOSFETs to switch output signals. The design features a strip of semiconductor material functioning as the gate of the MOSFET, which does not form a closed loop. The gates of two transistors are placed in series, introducing a delay between their activation. This delay is controlled by metal straps across selected transistor gates and feedback signals to adjust the current in the gates.
