... ADA4898-1/ADA4898-2 NOISE To analyze the noise performance of an amplifier circuit, identify the noise sources, and then determine if each source has a significant contribution to the overall noise performance of the amplifier. To simplify the noise calculations, noise spectral densities were used rather than actual voltages to leave bandwidth out of the expressions. Noise spectral density, which is generally expressed in nV/√ ...
