All analog-to-digital converters (ADCs) have a certain amount of input-referred noise—modeled as a noise source connected in series with the input of a noise-free ADC. Input-referred noise is not to be confused with quantization noise, which is only of interest when an ADC is processing ...
MT-004 TUTORIAL The Good, the Bad, and the Ugly Aspects of ADC Input Noise—Is No Noise Good Noise? by Walt Kester INTRODUCTION All analog-to-digital converters (ADCs) have a certain amount of "input-referred noise"— modeled as a noise source connected in series with the input of a ...
The designed IA achieved 26 nVrms input-referred noise (IRN) in the band of 0.1–10 Hz with 0.22 mm2 die area. The designed CA achieved 25 aCrms IRN in charge sensing mode and 19 fArms IRN in current sensing mode in the band of 0.01–1 Hz, respectively, and occupies 0.12 mm2 die ...
The internal connection sparsity was established at \(s=0.2\) (20%), with \(\alpha\), \(\beta\), and \(\sigma\) parameters configured to \(\alpha =0.1\), \(\beta =1.0\), and \(\sigma =0.01\), respectively. The noise \(\xi\) follows a normal distribution with a mean of ...

Unscented transformation method: The basic idea of UTM is to generate deterministically the appropriate number of samples of input RVs (referred to sigma points) by approximating their PDFs to equivalent PMFs such that both distributions have the same moments. It can easily incorporate the effect of...

The delta-sigma modulator based on a wide input signal range for recording biological signals and noise shaping SAR for input impedance amplification proposed in the present invention is a correlated double sampling integrator that increases CMRR and reduces noise, and amplifies the input impedance ...
Regarding the mirror, I have seen some references to using resistive loads in long tailed pairs for low noise (from memory in AoE chapter 3 and the 4625 data sheet). In LTSpice, adding the mirror decreased the input referred noise, and it did not show a significant contribution from those...
