Abstract:	In microwave phase-detectors for PLL applications, among the useful output signal a DC level appears, which has to be cancelled for a proper operation of the PLL's loop filter. In this paper we present a method for cancelling the offset level at the phase detector output, based on an external chang~ of the DC currents across each diode. The method can be implemented in a~ active or passive form. Experimental results are also presented.
