摘要： A control circuit for a step-up converter includes a soft start module configured to control states of N transistor pairs of the step-up converter, where N is an integer greater than two. A driver module is in communication with the soft start module and configured to generate a first signal when N transistor pairs of the step-up converter are ready to switch. A first charging circuit is configured to charge (N−1) capacitors of the step-up converter to an input voltage of the step-up converter in response to the first signal and to generate a second signal when charging is complete. A second charging circuit is configured to sequentially charge the (N−1) capacitors of the step-up converter to (N−1) predetermined voltage values in response to the first signal and the second signal and before operation of the step-up converter begins.

摘要： A power circuit includes a plurality of LED strings, each LED string having multiple LEDs connected in series. A plurality of magnetic amplifiers, reset current sources, and a control circuit are used to drive each LED string with equal current and to independently regulate the amount of voltage supplied to each LED to maximize efficiency. One magnetic amplifier, one reset current source, and one current sink are dedicated to each LED string. The control circuit measures the voltage drop across each LED string and determines an amount of reset control current in response to the measured voltage drop. The reset control current is supplied by the reset current source to the magnetic amplifier dedicated to the regulated LED string. The amount of reset control current supplied to the magnetic amplifier dictates the amount of voltage supplied to the LED string.

摘要： Presented are systems, devices, and methods for reliably authenticating asymmetric cryptography-based ICs based on Physically Unclonable Functions (PUFs) that are immune to reverse engineering. Various embodiments of the invention enhance the level of security in IC architectures without the need to connect to a remote certification authority, thereby, eliminating shortfalls associated with online authentication. Certain embodiments accomplish this by using a PUF-generated secure private key that need never be output by or exported from the PUF.

摘要： The present disclosure describes an ultraviolet (UV) sensor configured to detect a target UV spectrum (e.g., UVB spectrum). The UV sensor includes a first photodiode with a first UV spectral response and a second photodiode with a second UV spectral response. A filter layer having a graded spectral response is formed over the second photodiode, and the second UV spectral response is affected by a controlled parameter (e.g., thickness) of the filter layer. The UV sensor further includes a subtraction circuit coupled with the first photodiode and the second photodiode. The subtraction circuit is configured to provide a differential response based on a difference between the first UV spectral response and the second UV spectral response. The controlled parameter of the filter layer can be selected such that the differential response provides a detected spectral response of the target spectrum.

摘要： A method for gesture determination (e.g., discerning complex gestures) via an electronic system (e.g., a gesture sensing system) including an array of optical sensors is described herein. The method includes detecting a plurality of sub-gestures (e.g., simple gestures provided by a target located proximate to the system) via the array of optical sensors. The sensors generate signals based upon the detected (e.g., received) sub-gestures and transmit the signals to a processor of the gesture sensing system. The processor processes the signals to obtain data associated with the sub-gestures and analyzes the sub-gesture data to determine if the sub-gestures collectively constitute a gesture (e.g., complex gesture). When the analyzing indicates that the sub-gestures collectively constitute a complex gesture, the gesture sensing system detects the complex gesture.

摘要： Various embodiments of the invention implement countermeasures designed to withstand attacks by potential intruders who seek partial or full retrieval of elliptic curve secrets by using known methods that exploit system vulnerabilities, including elliptic operation differentiation, dummy operation detection, lattice attacks, and first real operation detection. Various embodiments of the invention provide resistance against side-channel attacks, such as sample power analysis, caused by the detectability of scalar values from information leaked during regular operation flow that would otherwise compromise system security. In certain embodiments, system immunity is maintained by performing elliptic scalar operations that use secret-independent operation flow in a secure Elliptic Curve Cryptosystem.
