According to one embodiment, a transmitter includes a first buffer, a second buffer, a logic circuit, and a class E power amplifier. The first buffer receives a first sinusoidal signal, and converts the first sinusoidal signal to a first rectangular wave signal. The second buffer receives a second sinusoidal signal having a phase delay with respect to the first sinusoidal signal, and converts the second sinusoidal signal to a second rectangular wave signal. The logic circuit receives the first and second rectangular wave signals, and performs logical operation processing on the first and second rectangular wave signals to generate a logic signal with a predetermined duty cycle. The class E power amplifier receives the logic signal, and performs amplification operation based on the logic signal. |
