  "textContent": "A wireless power system is described. The wireless power system includes a coil for receiving and transmitting wireless power, an integrated circuit, and one or more batteries. The integrated circuit includes 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 the wireless power system is in receive mode and further transmits alternating current to the coil when the wireless power system is in transmit mode. The current sense amplifier circuit detects a current flowing between the rectifier and the voltage regulator. The calibration circuit generates a voltage which is used by firmware of the integrated circuit to calibrate for aging of resistors within the current sense amplifier circuit.",
