1. A zero intermediate frequency receiver comprising a local frequency generating arrangement which is coupled to a pair of quadrature related mixers for mixing down a received signal to a pair of quadrature related signals to be demodulated in an in-phase signal path and in a quadrature signal path, a path comprising a cascade of at least one low pass filter and at least two amplifiers, and a first DC-offset correction circuit between the amplifiers, characterized in that the path comprises at least a second DC-offset correction circuit which is distributed over the path for allowing the path to have a high gain.
