ABSTRACT:
A circuit configuration for parameter adjustment has one or more first analog multipliers which receive an input signals and a control signal which cooresponds to a parameter, and which output output signals. A second multiplier, which is identical to the first multiplier, receives a first reference signal and a second control signal which corresponds to the first control signal, and outputs an output signal. A regulating device compares the output signal of the second multiplier with a second reference signal and derives the control signals therefrom.
