Amplifier suitable for receiving high-level signals

Abstract

The invention discloses an amplifier suitable for receiving high-level signals. The amplifier comprises a signal amplifying device and a control device, wherein an input end of the signal amplifying device is connected with an input signal; an output end of the signal amplifying device is used for outputting an amplified signal; an input end of the control device is connected with the output end of the signal amplifying device; and the control device is used for controlling the magnitude of a signal level at the input end of the signal amplifying device according to the magnitude of a level of the signal amplified by the signal amplifying device in order to ensure normal work of the signal amplifying device. The amplifier has the advantages that the problem that an existing conventional amplifier cannot work normally when the level of the input signal is high is solved. Meanwhile, the amplifier is particularly suitable for receiving the high-level signals, and has the characteristics of simple structure, firmness, durability and convenience in production. The problem that the amplifier is prone to be damaged in the case of the high-level signals is solved.
