Title: The Innovations of David H. Allen
Introduction
David H. Allen is a notable inventor based in Eagan, MN (US). He has made significant contributions to the field of VLSI technology, holding 2 patents that showcase his innovative spirit and technical expertise. His work primarily focuses on enhancing the functionality and efficiency of VLSI chips.
Latest Patents
One of David's latest patents is the "Flexible VLSI on-chip maintenance and test system with unit I/O cell." This application describes a peripheral cell structure for VLSI chips that utilizes standard cells with both input and output capabilities connected to nearly all signal-carrying pins. The functionality of these cells can be altered by control signals originating from a control register. Additionally, the clock input signal is divided into two independent signals to selectively disable the input or output registers, allowing for changes in the control register without affecting the contents of the other registers. An early signal is also provided to prepare for mode changes.
Another significant patent is the "Ring oscillator," which presents an improved design for VLSI chips formed at the chip periphery. This oscillator may include specific initiation gates and additional parasitic capacitance to enhance accuracy. The circuit elements used for the ring are consistent with those used in more centralized circuits, demonstrating David's commitment to innovation in VLSI technology.
