  • Patent number: 10338619
    Abstract: A digitally-assisted voltage regulator includes a gate driver circuit and a compensation circuit. The voltage regulator digitizes the load profile, and uses the digital information to compensate for process and temperature variations. The voltage regulator outputs a regulated voltage signal and one or more control signals based on a supply voltage and a reference voltage. The gate driver circuit receives the regulated voltage signal and generates a gate driver signal. The compensation circuit receives the control signal and generates first and second compensation signals. The voltage regulator regulates a voltage level of the regulated voltage signal using the regulator compensation signal, and controls a ramp-rate of the gate driver signal using the second compensation signal.

  • Patent number: 10341098
    Abstract: A method is provided for performing elliptic curve cryptography that reduces the number of required computations to produce, for example, a key pair. The number of computations is reduced by changing how a random nonce used in the computations is selected. In an embodiment, a look-up table is generated having pre-computed scalar values and elliptic curve points. Every time a new pseudo-random value is created for use in the ECDSA, a combination of the look-up table values is used to create multiple intermediate values. One of the multiple intermediate values is randomly chosen as a replacement value for one of the existing table entries. Each time the look-up table is used, multiple entries in the look-up table are updated to new look-up table values as described. In this manner, new randomness is provided in every step to generate the next pseudo-random nonce as a combination of multiple internally stored temporary look-up table values. Alternately, another mathematical group may be used.
