Amplifier arrangement and method of signal amplification |
摘要 |
An amplifier arrangement is proposed which has an amplifier with adjustable amplification having an output. An impedance transformer circuit is connected to the output. Said circuit is designed for transforming a high output impedance of the adjustable amplifier into a low impedance at its output. The amplifier arrangement contains at least two switchable elements having a reactance, which elements are connected in each case by a first terminal to the output of the impedance transformer circuit, and by a second terminal to a reference potential terminal. The switchable elements are designed for changing the impedance at the output of the impedance transformer circuit depending on a switch position of a switching means. A load impedance at the output of the amplifier is consequently varied by simple means when the output level of the amplifier changes.
