摘要： A voltage across a capacitor provides a supply voltage for circuits in an integrated circuit used to control a switching voltage regulator. The capacitor is charged during an OFF portion of a pulse width modulated (PWM) control signal that controls a first transistor in the switching voltage regulator. The voltage across the capacitor is controlled to be between a high threshold and a low threshold. The voltage is controlled by comparing the voltage across the capacitor to a low threshold and charging the capacitor during the OFF portion of the PWM signal if the voltage across the capacitor is below the low threshold. The voltage across the capacitor is compared to a high threshold and the capacitor is not charged if the voltage across the capacitor is above the high threshold.

摘要： An input digital signal is converted to an analog signal using a main digital to analog converter (DAC) and a sub DAC. An offset value is subtracted from the input digital signal to generate an offset adjusted digital signal. The main DAC converts the offset adjusted digital signal to a first analog signal. A second digital signal is generated based on the offset value and a correction factor determined, at least in part, during calibration of the main DAC. The sub DAC converts the second digital to a second analog signal, which when combined with the first analog signal, provides an analog representation of the input digital signal.

摘要： Techniques are disclosed relating to charging and discharging gates of transistors. In one embodiment, an apparatus includes first and second drivers. The first driver is configured to discharge a gate of a first transistor, and to send a charge indication to the second driver in response to reaching a Miller plateau for the first transistor. The second driver is configured to charge a gate of a second transistor above a threshold voltage in response to receiving the charge indication. In some embodiments, the second driver is configured to begin charging the gate of the second transistor to a voltage below the threshold voltage when the first driver begins discharging the gate of the first transistor begins, and to wait to charge the gate of the second transistor above the threshold voltage until the charge indication has been received.

摘要： A capacitor is charged synchronously with the beginning of an ON portion of a pulse width modulated (PWM) signal to generate a voltage across the capacitor using charging current sourced from an inductor on a primary side of a transformer. The voltage is supplied as a supply voltage to control circuitry in an integrated circuit used to generate the pulse width modulated signal. The charging is stopped when either the charging current goes above a predetermined charging current level or when the capacitor voltage goes above a predetermined capacitor voltage.

摘要： The invention relates to an integrated high power sine wave carrier circuit for outputting a low distortion high power sine wave. The circuit is used for antennas, and especially for antennas in automotive appliances. The circuit comprises a H-bridge (2) with matched power transistors (4, 6, 8, 10), a sine generator (24) for driving the H-bridge and a regulator (22) for sensing the power applied to the antenna and controlling the current amplitude of the sine wave output by the sine generator. The circuit operates under partial time-working, whereby the integration circuit is turned on or off. The circuit therefore comprises a shutdown pin, for shutting the circuit down in order to allow cooling. The partial time operation allows the circuit to be integrated on a single die.
