Integrated RC filter comprising a first resistor being coupled to a first capacitor through a first node, a signal input of said integrated RC filter being coupled through one ofthe first resistor and the first capacitor to the first node. To allow for an increase in the RC timeconstant τ of the RC filter without losing signal transparency, amplification means are included between said signal input and said one of the first resistor and the first capacitor having a gain factor substantially larger than unity, said first node being coupled through attenuation means to a signal output, said attenuation means having an attenuation factor substantially corresponding to said gain factor.
