My thesis work is focusing on the RF signal direct sampling reception after the antenna in a software-defined radio applications and cognitive radio context. The purpose of this technique is to treat the signal whatever the modulation used and in a wide range of frequencies, directly after the antenna while minimizing at maximum the analog part. For this, a passive sampler architecture has been used. The originality of this architecture consists in the implementation of a passive differential sampling system working in quadrature, consisting of a switched capacitors network. By setting the time system constant to a high value compared to the minimum frequency of the RF signal to be demodulated , the sampler acts both as a filter and a frequ...
