Patent ID: 6999745

Claim:
A receiver ( 1 ) comprising an input for receiving a first signal (RF), said receiver further comprising a local oscillator ( 25 ) for generating a periodical signal (LO), the receiver ( 1 ) further comprises a mixer ( 20 ) for generating a third signal (I M ) representative for a combination of a second signal (I RF ) and the periodical signal (LO), said receiver ( 1 ) being characterized in that the receiver ( 1 ) further comprises a voltage to current converter ( 10 ) for receiving the first signal (RF) and generating the second signal (I RF ) as a current indicative for the first signal (RF), the mixer ( 20 ) comprises a plurality of controllable switches, the receiver ( 1 ) farther comprises a variable gain current to voltage converter (VGIV) ( 30 ) coupled to the mixer ( 20 ), the VGIV ( 30 ) receiving the third signal (I M ) and generating a first voltage signal (V F ), said first voltage signal being in a linear relationship with the third signal (I M ).
