ABSTRACT:
A receiver comprising an input for receiving a first signal, said receiver further comprising a local oscillator for generating a periodical signal. The receiver further comprises a mixer for generating a third signal representative for a combination of a second signal and the periodical signal. The receiver is characterized in that it further comprises a voltage to current converter for receiving the first signal and generating the second signal as a current indicative for the first signal. The mixer comprises a plurality of controllable switches. The receiver further comprises a variable gain current to voltage converter (VGIV) coupled to the passive mixer, the VGIV receiving the third signal and generating a first voltage signal, said first voltage signal being in a linear relationship with the third signal.
