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 ...

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 ...

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.

Previous installments of this article series discussed the need to verify SPICE model accuracy and how to measure the output impedance, small-signal bandwidth, and input-referred errors of operational ...

Members can download this article in PDF format. In designing an input stage for an analog-to-digital converter (ADC), engineers choose a particular amplifier, assign a target gain, and note the ...
