  "textContent": "An integrated circuit is described. This integrated circuit may include a wireless-charger transmitter, which includes a driver circuit electrically coupled to multiple branches associated with multiple transmission coils. A given branch may include or may be electrically coupled to: a capacitor, a multiplexor (MUX) switch that includes a single field-effect transistor (FET) or a single integrated-gate bipolar transistor (IGBT), and a given transmission coil. Moreover, the wireless-charger transmitter may include a control circuit that provides control signals to gates of FETs or the IGBTs in the branches that selectively activate at least the MUX switch in the given branch and selectively deactivate remaining MUX switches in a remainder of the branches. Furthermore, the driver circuit may perform wireless charging by driving the given transmission coil in the activated given branch using an electrical signal having a fundamental frequency component.",
