The invention relates to an analog quadrature demodulator ( 100 ), which comprises analog domain means for splitting an incoming signal into an in-phase (I) branch signal and a quadrature (Q) branch signal and an analog domain correction circuitry ( 106, 107 ) for controllably causing the in-phase (I) branch signal and the quadrature (Q) branch signal to co-operate with each other via the correction circuitry ( 106, 107 ) so as to correct the quadrature error.
