Signal Chain Noise Analysis for RF-to-Digital Receivers
Design Note 439
Cheng-Wei Pei
Introduction
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 applicationвЂ™s noise
requirement has a signiп¬Ѓcant inп¬‚uence 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 is translating between the various units used by the
components in the chain: namely the RF, IF/baseband,
and digital (ADC) sections of the circuit.
Figure 1 shows a simpliп¬Ѓed system diagram. There is
an RF section, an IF/baseband section (represented
by an ampliп¬Ѓer) and an ADC. The RF section, which
includes a mixer or demodulator, is commonly speciп¬Ѓed
using noise п¬Ѓgure (NF) in a decibel scale (dB). This may
also be speciп¬Ѓed with a noise power spectral density
which is similar to NF in concept (e.g., вЂ“160dBm/Hz is
