A method for configuring low-noise integrated amplifier circuits having an input stage with a transistor includes noise matching the circuit to the real part of a predetermined output impedance of a transfer element connected upstream of the circuit by a choice of process parameters during the production of the circuit and/or of geometry parameters of the integrated components and/or dimensioning the component values of the circuit, the noise figure of the circuit, dependent on a real generator resistance, is less than a predetermined figure in a range wherein the value of the output impedance real part also lies. The required power matching of the input impedance of the circuit to the output impedance is performed by choosing the effective load on a transistor collector to produce a complex voltage gain that, due to the Miller effect, generates an input impedance equal to the complex conjugate of the predetermined output impedance.
