Front end strategy for the DAQ system of a Kinetic Inductance Detector

Cosmic microwave background radiation anisotropies calls for extreme precision measurement of photon energy in the range of 70 to 900 GHz. Kinetic Inductance Detectors (KID) are able to reduce the effects of the radiative noise. In this paper we describe the Front-End electronics architecture we adopted for the Data Acquisition System of a Kinetic Inductance Detector.
