Noise analysis in super-regenerative receiver systems
The recent increase in the need for energy efficient wireless nodes have led to the study of various low power consumption receiver and transmitter architectures. The super-regenerative receiver architecture is one of the possible candidates for such a low power application. In this paper a detailed study on the noise analysis for such a kind of receiver is carried out. A closed form representation of the output signal to noise ratio for both narrow-band and wide-band communication is derived. The result indicates for a narrow-band communication the output signal to noise ratio cannot be better than a normal tuned amplifier. In the wide-band mode the SNR of super-regenerative receiver in linear regime is similar to a tuned amplifier. ©2008 IEEE.
