<p>An input circuit of for example (a tuner of) a radio receiver has to receive an input signal, for example, from an antenna and having filter means coupled to the input. Such an input circuit further comprises an amplifier and an output stage for supplying an output signal to a mixer circuit. To improve the operation of such an input circuit an inductive feedback is proposed, resulting in a flat frequency response.</p> |
