Abstract: The amplifier stage of the invention has a first and a second differential amplifier branch and a first and a second impedance-burdened branch. The first impedance-burdened branch is connected in parallel with the input impedance of the first differential amplifier branch, and the second impedance-burdened branch is connected in parallel with the input impedance of the second differential amplifier branch. As a result, it is possible to maintain the amplifier parameters largely constant.

Abstract: An electrical circuit is provided for controlling nonlinear paths. A first linearization block and a second linearization block are provided, which may each have a characteristic curve that is the inverse of that of the control path. The first linearization block is configured in a feedback path running from the output of the control path to an input of a regulator. The second linearization block is configured for supplying a reference variable to an input of the regulator. Nonlinearities in the control path are thus linearized. In consequence, major changes in the reference variable are acceptable. The linearization blocks can be designed in a simple manner and require only a small surface area, since low power levels are normally produced at the inputs of an operational amplifier contained in the regulator. An additional advantage resulting from this is compensation for temperature drift of the two linearization blocks. The described regulator is suitable, for example, for controlling a transmission amplifier, as is used in mobile radio applications.
