| 摘要 |
The present invention relates to an amplifying apparatus and has one of the objects to control (optimize), in an amplifier having a circuit constant determined so as to satisfy the condition of E-class operation, the circuit constant (e.g., the capacity of a capacitor) in accordance with an output power from the amplifier. For the above, the amplifying apparatus of the present invention includes an amplifier (20) having a circuit constant determined so as to satisfy a condition for E-class operation; power detecting means (17, and 18) which detects an output electricity from the amplifier; and controlling means (19) which controls the circuit constant in accordance with the output power detected by the power detecting means.
