摘要： An embodiment of the present disclosure relates to a method of detection of a touch contact by a sensor including a first step of comparison of a voltage with a first voltage threshold; and a second step of comparison of the voltage with a second voltage threshold, the second step being implemented if the first voltage threshold has been reached within a duration shorter than a first duration threshold, the second voltage threshold being higher than the first voltage threshold.

摘要： System, method, and circuitry for generating content for a programmable computing device based on user-selected configuration information. A settings registry is generated based on the user's selections. The settings registry and the user selected configuration information is utilized to generate the content, such as code, data, parameters, settings, etc. When the content is provided to the programmable computing device, the content initializes, configures, or controls one or more software and hardware aspects of the programmable computing device, such as boot sequence configurations, internal peripheral configurations, states of the programmable computing device, transitions between states of the programmable computing device, etc., and various combinations thereof.

摘要： A method for controlling a signal envelope shape of modulation pulses in a driver of a wireless transmitter includes supplying a first voltage to the driver during a non-modulated state, supplying a second voltage configurable by a configurable modulation index value to the driver during a modulated state, switching between the non-modulated state and the modulated state comprising setting the modulation index value to configure the second voltage level at the same level as the first voltage and then switching between supplying the first voltage to the driver and supplying the second voltage to the driver, and filtering to a limited bandwidth the variations of the second voltage resulting from configuring the modulation index value.

摘要： A method is provided to access a data storage memory that stores data signals in a plurality of indexed memory locations. An access control circuit receives a memory access request signals from a processing circuit. The method includes replicating the respective memory access request signals to provide for each a respective replicated memory access request signal, accessing indexed internal memory locations to retrieve a first data signal retrieved as a function of the respective memory access request signal and a second data signal retrieved as a function of the respective replicated memory access request signal, and checking for identity the first data signal and the at least one second data signal. The access control circuit transmits to the processing circuit a data signal or an integrity error flag signal as a result of the identity check.

摘要： A control circuit for a voltage source generates a reference signal for a voltage source, wherein the reference signal indicates a requested output voltage to be generated by the voltage source. A digital feed-forward control circuit computes a digital feed-forward regulation value indicative of a requested output voltage by determining a maximum voltage drop at strings of solid-state light sources. A digital feed-back control circuit determines a minimum voltage drop for current regulators/limiters for the strings and determines a digital feed-back correction value as a function of the minimum voltage drop. The control circuit then sets the reference signal after a start-up as a function of the digital feed-forward regulation value and corrects the reference signal as a function of the digital feed-back correction value.

摘要： A testing tool includes a clock generation circuit generating a test clock and outputting the test clock via a test clock output pad, data processing circuitry clocked by the test clock, and data output circuitry receiving data output from the data processing circuitry and outputting the data via an input/output (IO) pad, the data output circuitry being clocked by the test clock. The testing tool also includes a programmable delay circuit generating a delayed version of the test clock, and data input circuitry receiving data input via the IO pad, the data input circuitry clocked by the delayed version of the test clock. The delayed version of the test clock is delayed to compensate for delay between transmission of a pulse of the test clock via the test clock output pad to an external computer and receipt of the data input from the external computer via the IO pad.

摘要： An embodiment driver circuit comprises a power supply pin configured to receive a power supply voltage, and a set of control pins configured to provide a set of control signals for controlling switching of a set of switches of an h-bridge circuit comprising a pair of high-side switches and a pair of low-side switches. The driver circuit comprises control circuitry coupled to the control pins and configured to generate the control signals, and sensing circuitry coupled to the power supply pin and configured to generate a detection signal indicative of the power supply voltage exceeding a threshold value. The control circuitry is sensitive to the detection signal and is configured to generate the control signals to activate one of the pair of high-side switches and the pair of low-side switches and de-activate the other of the pair of high-side switches and the pair of low-side switches.

摘要： A circuit for controlling a first plurality of transistors connected in parallel and a second plurality of transistors connected in parallel, includes: a first plurality of stages, a respective one of the first plurality of stages being configured to supply a first control signal to a respective one of the first plurality of transistors; and a second plurality of stages, a respective one of the second plurality of stages being configured to supply a second control signal to a respective one of the second plurality of transistors. An output current of the respective one of the first plurality of stages is regulated based on a difference between a first value representative of a sum of output currents of each stage of the first plurality of stages and a second value representative of a sum of set points assigned to the first plurality of stages.
