1. A method for processing signals, the method comprising:

  • performing using one or more processors and/or circuits;

    comparing an amplitude voltage and a DC reference voltage associated with an in-phase (I) component and a quadrature (Q) component of a signal;

    adjusting said amplitude voltage associated with one or both of;

    said I component and/or said Q component based on said comparison; and

    controlling a programmable current source based on said comparison.
