The noise incurred by reducing the wordlength is substantial. (The noise in a 1-bit system is about 90 dB higher than the noise in a 16-bit system, for example.) Noise shaping distributes that noise in a high-pass fashion, but it does not reduce the total noise level. In …

MT-047: Op Amp Noise - Analog Devices


Before discussing op amp current noise, it is important to understand that practical op amp circuits require external resistors, and all resistors have a Johnson noise of √(4kTBR), where k is Boltzmann's Constant (1.38×10–23J/K), T is the absolute temperature, B is the bandwidth, and R is the resistance.
