Abstract

The arrangement is for regulating the temperature in an amplifier which has a temperature coefficient, an input signal and an output signal. It has a first and a second component, each with its own temperature coefficient (TK1,TK2). Each component produces a signal, which is dependent upon the component own temperature coefficient. A component multiplies each of the signals with a respective regulating signal (a,b). The two signals are added together. A component then multiplies the added result with the input signal to the amplifier, resulting in an output signal dependent upon the two regulating signals and the temperature coefficients of the components. The first component signal represents the entity 1 + Tk1asterisk(T1-T0), where T1 is the temperature in the first component and T0 is a selected reference temperature. The signal from the second component represents the entity 1+Tk2asterisk (T2-T0), where T2 is the temperature in the second component and T0 is the selected reference temperature. The result of the addition of these two signals is equal to a asterisk '1 = TK1asterisk (T-T0) = basterisk (1 = Tk2 (T-T0). T1 = T2.
