Method of correcting the output signal of an analog amplifier, amplifier module and measuring device
摘要:
A method is disclosed for correcting transfer errors of an analog amplifier that occur following a jump in the amplifier input signal caused by switching. A measuring device includes at least one sensor as well as a signal-processing unit connected to the sensor and analog amplifier. The signal-processing unit includes at least one modulator and/or a multiplexer, an analog amplifier and at least one processing stage following the analog amplifier in the circuit chain. The processing stage, dependent on the point in time when the switching jump occurs, is separated from the latter during a predetermined timeout phase duration by means of a switch that is arranged between the analog amplifier and the processing stage and is controlled by a timeout controller, and/or dependent on the point in time when the switching jump occurs, said processing stage is blocked by a timeout controller during a predetermined timeout phase duration.
