ADC Noise: More on the Analog Inputs

In the last two blogs, we looked at calculating the noise contribution from the driving amplifier to the total ADC noise in terms of the overall SNR (signal to noise ratio). I stepped through the ...

ADC SNR effects due to parasitics, mismatch, and noise

Successive-approximation-register (SAR) analog-to-digital converters (ADCs) are commonly used in applications which require medium to high resolution. The major benefits of SAR ADCs are high ...

Using input-referred noise to improve analog-to-digital converter resolution

All analog-to-digital converters (ADCs) have a certain amount ofinput-referred noise. In most cases,less input noise is better. There are some cases, however, where inputnoise can actually be helpful ...

Sounding out input noise on ADCs

All analogue-to-digital converters (ADCs) have a certain amount of input-referred noise. Input-referred noise is not to be confused with quantisation noise, which is only of interest when an ADC is ...
