Analog-to-digital converters (ADCs) perform conversions by comparing the input voltage level against the reference input; therefore, the accuracy, stability and noise of the reference directly affect ...

There are different methods to measure current. One method is to use a resistor across a current output and measure the voltage. The voltage across the resistor is measured using ohm's law: where I is ...

In this article, we highlight one of the most important architectural traits of new continuous-time sigma-delta (CTSD) precision ADCs: the easy to drive resistive input and reference. The key to ...

Today's analog system designers face many design challenges. Not only do designers need to select the proper integrated-circuit components, but they also must accurately predict the interactions of ...

When considering any new part in the signal chain, input/output impedance is usually an important spec to “bolt” the necessary signal-chain blocks together properly. For a high-speed converter, this ...

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 ...

Analog filter design remains a cornerstone of modern signal processing, instrumental in a vast array of applications spanning telecommunications, instrumentation, and biomedical engineering. Recent ...
