Signal chain noise analysis for RF-to-digital receivers is discussed.
Designers of signal receiver systems often need to perform cascaded chain analysis of system performance from the antenna all the way to the ADC. Noise is a critical parameter in the chain analysis because it limits the overall sensitivity of the receiver. An application’s noise requirement has a significant influence on the system topology, since the choice of topology strives to optimize the overall signal-to-noise ratio, dynamic range and several other parameters. One problem in noise calculations ...
