摘要:
An amplifier arrangement with controllable gain includes a first and a second amplifier device which each have a control input to receive a control signal to adjust a gain factor of the respective amplifier device. A control device is provided which is coupled to the second amplifier device to derive an effective gain factor of the second amplifier device as a function of the control signal. The control device further includes a control output coupled to the respective control inputs of the first and the second amplifier device to provide the control signal depending on a desired gain factor and the effective gain factor.
