Abstract

There is provided a method that comprises identifying a parasitic signal transfer in a filter using a signal-directed graph; and adding compensation paths to the filter to reduce or eliminate the effect of the parasitic signal transfer. A corresponding filter is provided which comprises a plurality of amplifier stages that generate one or more filter poles; at least one component coupled to at least one of the amplifier stages, the component causing a parasitic effect in the filter; and means for applying a compensation current to the at least one amplifier stage to reduce or eliminate the parasitic effect. A radio receiver is further provided that comprises a filter for receiving and filtering in-phase and quadrature signals; an amplifier for receiving and amplifying one of said filtered in-phase and quadrature signals; means for receiving the amplified and filtered in-phase or quadrature signal from said amplifier, and for regenerating the other one of said in-phase and quadrature signals from said amplified and filtered signal.
