Abstract
An active I/Q generator circuit comprises an input node for receiving a reference oscillation signal. The circuit has an I-output and a Q-output for respectively outputting an I-signal and a Q-signal. A first active component is electrically coupled to the input node and arranged to amplify the reference oscillation signal and to output an amplified reference oscillation signal. A second active component is electrically coupled to the first active component to receive the amplified reference oscillation signal. The second active component is arranged to generate, based on the amplified reference oscillation signal, an in-phase signal and a, with respect to the in-phase signal, phase shifted signal, the second active component electrically coupled to the in-phase signal output for providing the in-phase signal and electrically coupled to the quadrature-phase output for providing the phase-shifted signal.
