equivalent noise input (ENI)

Equivalent Noise Input (ENI) is a characteristic value of low-noise amplifiers and preamplifiers that takes into account the inherent noise of the amplifier.

The equivalent input noise is composed of the noise bandwidth of the amplifier and the inherent noise and is specified in dBm. The equivalent input noise is calculated from the logarithm (10log) of the noise bandwidth, specified in Hertz, plus the inherent noise, specified in decibels( dB).
