Abstract: A low drop-out voltage regulator, an integrated circuit, a sensor and a method of providing a regulated voltage are provided. The low drop-out voltage regulator comprises a regulated voltage driver for providing the regulated voltage in response to a control voltage, a feedback-loop circuit for generating the control signal such that the regulated voltage driving circuit provides the regulated voltage, and a pull-up circuit for pulling up the regulated voltage to a supply voltage when a difference between the supply voltage and the control voltage is smaller than a predetermined threshold value. In the feedback-loop circuit a first feedback voltage or a second feedback voltage is generated, respectively, on basis of a first ratio and a second ratio between the feedback voltage and the regulated voltage. The second feedback voltage is generated instead of the first feedback voltage when the regulated voltage is pulled-up to the supply voltage.
Abstract: A gate drive circuit includes a first switch and a first capacitor. A first terminal of the first capacitor is electrically coupled to the first switch. The first switch is electrically coupled between the first terminal and a voltage supply of the power transistor. A second terminal of the first capacitor is electrically coupled to the reference potential. The gate drive circuit further includes a first voltage limiter in parallel with the first capacitor. The first voltage limiter limits a voltage across the first capacitor to a first predetermined voltage. The gate drive circuit further includes a second capacitor, a pre-charging circuit arranged between the first terminal of the first capacitor and a first terminal of the second capacitor. The gate drive circuit further includes a third capacitor with a first terminal electrically coupled to a second terminal of the second capacitor and a second terminal electrically coupled to a gate terminal of the power transistor.
Abstract: A power factor corrector raises power factor at low loads or high mains voltages by modifying the switch timing or the current received by the power converter. It achieves this by increasing the switch-on time of a control switch during the falling time so that the majority of the switch-on time during a mains period occurs during the falling time, to thereby control the current received by the converter to compensate for current received by the intermediate filter. Some embodiments may employ a feedback system to produce one or more error signals that modify the control signal used to control the operation of the converter. Various embodiments may also include additional stages that limit the compensation range of the error signal.
Abstract: A method for testing a plurality of pressure sensors on a device wafer includes placing a diaphragm of one of the pressure sensors on the device wafer in proximity to a nozzle of a test system. A pneumatic pressure stimulus is applied to the diaphragm via an outlet of the nozzle and a cavity pressure is measured within a cavity associated with the pressure sensor in response to application of the pneumatic pressure stimulus. The pneumatic pressure stimulus within the cavity corresponds to the pressure applied to the diaphragm. Methodology is executed to test the strength and/or stiffness of the diaphragm. Additionally, the methodology and test system can be utilized to determine an individual calibration factor for each pressure sensor on the device wafer.

As an example, one apparatus includes a first clock generation circuit configured to generate a first clock signal with a frequency spectrum having a first frequency range.

The second clock signal has a frequency spectrum extending outside of the frequency range. The apparatus includes a third circuit configured to regulate a voltage at a supply node as a function of the second clock signal. A current regulation circuit is configured to regulate current in a circuit path, from the supply node and passing through a load circuit coupled to the current regulator, as a function of the first clock signal.

Abstract: A controller device can control the time of a slave sub-system in a chain in a base station system. The controller device comprises a slave transceiver for receiving/transmitting from/to a master sub-system, and a synchronization device for synchronizing a clock of the slave transceiver to a clock of the master sub-system based on the received signal received from the master sub-system. The synchronization circuitry comprises a clock input port for receiving an external clock signal from an external clock generator. At a received signal input port the received signal can be received from the master transceiver. A tracking loop couples the received signal input and the second phase input to a control input of a controllable PLL, for providing a negative feedback which controls a phase and/or frequency of the feedback signal to counter the phase and or frequency error between the external clock signal and the received signal.

Abstract: A receiver component and a method for enhancing a detection range of a time synchronization process in a receiver utilize multiple cross-correlations of a received signal with a known preamble sequence. The results of the multiple cross-correlations are divided into delay segments. The delay segments of one of the multiple cross-correlations are compared with the delay segments of another of the multiple cross-correlations to determine delay of the delay segments of the one of the multiple cross-correlation results.
Abstract: A method of wireless communication, with a circuit that includes a radio frequency identification (RFID) reader, can be carried out using a circuit that is configured and arranged to communicate with RFID cards that use load modulation of an RF carrier provided by the RFID reader. A presence of the radio frequency (RF) carrier is detected on an antenna. A local clock signal is generated. A difference between the local clock signal and the RF carrier is detected. In response to the detected difference, the frequency of the local clock signal is modified to reduce the detected difference. Load modulation of the RF carrier is mimicked by modulating the local clock signal to encode data; and driving the antenna with the modulated local clock signal.
