Abstract: A wireless charging transmitter device is includes a square wave signal generation circuit. The square wave signal generation circuit is formed by a first PMOS transistor switching circuit having a group of PMOS performance transistors and at least one PMOS functionality transistor, and a second NMOS transistor switching circuit having a group of NMOS performance transistors and at least one NMOS functionality transistor.
