Analog signal conditioning

An analog conditioning circuit and a corresponding method for processing an analog input signal provide a conditioned analog signal for input into an analog processing circuit. The analog conditioning circuit comprises a main signal path between an input for receiving the analog input signal and an output for outputting the conditioned analog signal, wherein the transfer function of the main signal path is constrained by a transfer function requirement associated with the analog processing circuit; and a feedforward signal path comprising a first filtering block configured to attenuate desired frequencies of a first signal derived from the analog input signal to provide a filtered analog signal; wherein the feedforward signal path is configured to input the filtered analog signal into the main signal path such that the filtered analog signal is subtracted from a second signal derived from the analog input signal to provide the conditioned analog signal.
