Patent ID: 11843361

Abstract:
A processor may calibrate a first actuator electrically coupled to a transconductance stage of the frequency conversion circuit. The transconductance stage may be configured to receive a differential signal input. Calibrating a first actuator may adjust a first basis vector associated with a differential direct current (DC) output of the transconductance stage. A processor may calibrate a second actuator electrically coupled to receive the differential current output of the transconductance stage and electrically coupled to a set of commutating devices of the frequency conversion circuit. The commutating devices may be configured to receive differential LO inputs. Calibrating a second actuator may adjust a second basis vector associated with a differential impedance of the set of commutating devices. A processor may offset responsive to adjusting the first basis vector and the second basis vector, the first leakage basis vector and second leakage basis vector of the LO leakage signal.
