Abstract: A wireless power receiver includes circuitry configured to receive a wirelessly induced voltage from a wireless power transmitter via a magnetically induced connection with the wireless power transmitter. It is determined that an overvoltage condition exists when the wirelessly induced voltage exceeds a threshold voltage, and the wirelessly induced voltage is reduced in response to determining that the overvoltage condition exists. The circuitry communicates the overvoltage condition to the wireless power transmitter via the magnetically induced connection while over-voltage protection is enabled.

Abstract: Systems and methods for enhancing slew control of output signals. An output driver receives an input signal and controllably increases the gain of that signal to provide a high quality output signal for use by an electronic device coupled thereto. The output driver includes an operational amplifier that maintains stability of the output signal through a feedback of the output signal. A control circuit supplies a signal to the output driver such that the driver to improve the shape of the output signal as the input signal is applied. After the operational amplifier regains control, the control circuit disengages. One embodiment of the present invention may be particularly useful as a USB output driver.

Abstract: Accurate models of the contact region of an integrated circuit resistor are created in a single function. The function incorporates many contact geometries into a single function that cannot otherwise be represented by a closed form solution. A method of creating the function uses regression over the simulation results for many combinations of input variables. The function may use the contact resistance, metal trace resistance, and resistive area resistance as inputs to calculate the resistor contact region resistance.

Abstract: A circuit which provides that a source voltage and a pad voltage are band-limited and source-followed down in order to get them into the input range of a comparator, the output of which signals an over-voltage condition on the pad. The circuit provides the ability to provide the relationship between the source voltage and pad voltage to a comparator with a very small, tightly-controlled offset. This translates to the ability to detect very small over-voltage conditions on an IO. The circuit consumes little power, is highly accurate, and requires no special, expensive process options. The circuit can be used anywhere there is a desire to compare (with a small, accurate offset) two signals that are close to a source voltage, such as VDD. The circuit can also be used to compare signals close to VSS.
