Controlling spot and integrated noise in a two-stage transimpedance design

A very common application is to use a low-noise, moderate-gain first stage in a sensor path, followed by a fully differential amplifier (FDA), to provide added gain and centering on the common-mode ...

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 ...

Practical Input-Referred Calculations in Precision Systems

Why input-referred calculations are valuable in gaining system insight. Why combining noise sources referred to input (RTI) and referred to output (RTO) is best to determine system performance.
