Abstract
This application provides an electronic device and a stylus in-position determining method. The electronic device includes: an inverter circuit. When a Q value of the transmit coil is detected, the controller controls the resonant capacitor adjustment circuit to operate; the Q value detection circuit is configured to obtain a voltage signal representing a Q value; and the controller obtains the Q value based on the voltage signal, and when the Q value is greater than a preset threshold, determines that a stylus is attached to the electronic device. The resonant capacitor adjustment circuit participates in operation during Q value detection.
