DYNAMIC LIMITING CIRCUIT FOR AMPLIFIER |
| 摘要 |
PURPOSE: To provide a device for dynamically restricting the gain of a circuit using an operational amplifier being a circuit which can possess an input signal that ordinarily overdrives amplifier output to a saturation condition. CONSTITUTION: The dynamic restriction amplifier contains the operational amplifier A having a non-inversion input terminal 22 and a inversion input terminal 24, an output terminal 26 and a dynamic restriction circuit 20 connected between the inversion input terminal 24 and the output terminal 26 of the operational amplifier A. The dynamic restriction circuit 20 operates to supply feedback current between the output terminal of the operational amplifier and the inversion input terminal of the operational amplifier when the output voltage of the operational amplifier A exceeds threshold potential. |
