Patent number: 10771062Abstract: Presented are systems and methods that allow hardware designers to protect valuable IP and information in the hardware domain in order to increase overall system security. In various embodiments of the invention this is accomplished by configuring logic gates of existing logic circuitry based on a key input. In certain embodiments, a logic function provides results that are dependent not only on input values but also on an encrypted logic key that determines connections for a given logic building block, such that the functionality of the logic function cannot be determined by reverse engineering. In some embodiments, the logic key is created by decrypting a piece of data using a secret or private key. Advantages of automatic encryption include that existing circuitry need not be re-implemented or re-built, and that the systems and methods presented are backward compatible with standard manufacturing tools.Type: GrantFiled: August 9, 2018Date of Patent: September 8, 2020Assignee: Maxim Integrated Products, Inc.Inventors: Robert Michael Muchsel, Donald Wood Loomis, III, Edward Tangkwai Ma, Hung Thanh Nguyen, Nancy Kow Iida, Mark Alan Lovell

Patent number: 10289186Abstract: Various embodiments of the invention allow to dynamically transition between clock-driven and even-driven circuit elements to enable automatic multi-mode operation to enable low-power and high-throughput applications. In certain embodiments, dynamic transitioning is accomplished through a mode control unit that evaluates input data from a number of sources to determine whether to initiate a transition. Certain embodiments take advantage of dynamic transitioning to allow for energy harvesting in a data gathering phase by switching to high power communication phase as needed. The energy harvesting scheme is particularly suited for battery-operated applications that benefit from a reduction in overall power consumption.Type: GrantFiled: February 24, 2014Date of Patent: May 14, 2019Assignee: Maxim Integrated Products, Inc.Inventors: Hung Thanh Nguyen, Nancy Kow Iida, Edward Tangkwai Ma, Robert Michael Muchsel, Gary Vernon Zanders

Patent number: 9513644Abstract: The invention relates to systems having linear regulators and methods of operating the systems. The system includes: a linear regulator responsive to an input voltage and operative to output a regulated voltage; a first circuit responsive to the regulated voltage and configured to operate at a first voltage difference between the regulated voltage and a ground level; and a second circuit responsive to the input voltage and the regulated voltage and configured to operate at a second voltage difference between the input voltage and the regulated voltage. The second circuit is coupled to the first circuit so that an entire portion of a current flowing through the second circuit is configured to enter into the first circuit during operation, wherein the current flowing through the second circuit bypasses the linear regulator.Type: GrantFiled: January 16, 2013Date of Patent: December 6, 2016Assignee: Maxim Integrated Products, Inc.Inventors: Sung Ung Kwak, Nancy Kow Iida, Edward Tangkwai Ma, Khankap Mounarath, Robert Michael Muchsel, Hung Thanh Nguyen, Gary Zanders
