Abstract
A receiving amplifier includes a semiconductor body with a first node, a second node and an amplifier circuit. The amplifier includes at least one field-effect transistor, a first input, and a second input. A capacitive element is arranged between the inputs of the amplifier circuit, and a tuned circuit whose resonant frequency can be tuned is connected upstream of the amplifier circuit and contains a variable-capacitance element that is connected in parallel with the element in the amplifier circuit. Two inductive elements are also provided, wherein the first inductive element is connected to the first node and the second inductive element is connected to the second node. This results in a series tuned circuit, which leads to a voltage increase at the resonant frequency, and results in an improved signal-to-noise ratio for a signal which is supplied to the receiving amplifier.
