1. An integrated RC filter comprising:

  • a first capacitora first resistor that is coupled to the first capacitor through a first node, a signal input of the integrated RC filter being coupled through one of the first resistor and the first capacitor to the first node,an amplifier that is coupled between the signal input and the one of the first resistor and the first capacitor, and has a fixed gain factor substantially larger than unity, andan attenuator that couples the first node to a signal output, and has a fixed attenuation factor to provide the RC filter with a fixed gain between the signal input and the signal output.
