Latest Patents

Ryan's latest patents include a "Current sensing circuit with integrated resistor and dual sense amplifiers." This invention describes a structure that incorporates two amplifiers in parallel. The first amplifier is an always-on amplifier that provides continual measurements of a current (Isns) across an integrated polysilicon resistor for one or more analog control loops. The second amplifier is a switched amplifier that measures the current (Isns) for one or more digital control loops. This switched amplifier is activated by one or more switches to perform offset measurements with high accuracy.

Another notable patent is "Aging compensation for poly-resistor based current sense amplifier." This invention outlines a wireless power system that includes a coil for receiving and transmitting wireless power, an integrated circuit, and one or more batteries. The integrated circuit features a rectifier circuit, a current sense amplifier circuit, a calibration circuit, and a voltage regulator. The rectifier circuit receives alternating current from the coil and generates a rectified voltage when in receive mode, while also transmitting alternating current to the coil in transmit mode. The current sense amplifier circuit detects the current flowing between the rectifier and the voltage regulator, and the calibration circuit generates a voltage used by the firmware to calibrate for aging of resistors within the current sense amplifier circuit.
