Circuit lets you test sample-and-hold amplifiers - measure voltage drop with a digital voltmeter
Design How-To  
6/29/2011   1 comment
Sample-and-hold amplifiers sample an analog voltage and hold it until an ADC can digitize it. A perfect sampling circuit holds a voltage until digitizing is complete. Thus, the amplifier’s output is identical to its input. Real sample-and-hold amplifiers, however, can gain or lose voltage, producing an error. Offset voltages in amplifiers cause a static additive error. Further, there occurs a specific additive error, the so-called voltage pedestal, which originates within the transition from th

For many engineers, solving a measurement problem is a matter of going back to the basics of switching. Here are some common switching-related error sources to consider when troubleshooting measurement problems.
Oscilloscopes and ENOB
Design How-To  
6/15/2011   12 comments
For scopes with bandwidth in the GHz range, one quality metric involves characterizing a scope’s analog-to-digital converter (ADC) using effective number of bits (ENOB). In a new design article added this week Joel Woodward and Brig Asay of Agilent Technologies explain that when selecting which scope to use, how important ENOB is and how effective ENOB is at predicting a scope’s measurement accuracy.
