摘要： PROBLEM TO BE SOLVED: To provide a class-E amplifier for preventing deterioration in efficiency due to the fluctuation in the power source voltage, by controlling the rise time/fall time at switching of a transistor for amplification, in response to fluctuation of a power source voltage.
SOLUTION: A high-frequency input signal, inputted from an input signal generator 5, is amplified by a transistor 4 forming the class E amplifier and supplied to a load R6. In this case, a power source voltage detecting unit 1 detects the voltage level of a power source voltage Vdd and supplies it to a control unit 2. A control unit 2 generates a control signal, corresponding to the voltage level of the power source voltage Vdd and causes the control signal to vary the capacity value of a variable capacitance Cp3. Thus, since the capacitance value of the variable capacitance Cp3 changes, according to the variation of the power source voltage Vdd, the rise time/fall time by switching of the transistor 4 can be controlled according to the power source voltage.

Also, the unit 6 holds the initialized gate voltage, when the drain voltage is not smaller than a second reference voltage higher than the first reference voltage, and controls the gate voltage so as to make the gate voltage proportional to the drain voltage, when the drain voltage is not larger than the second reference voltage.
