Previous installments of this series discussed the need to verify SPICE model accuracy and how to measure the output impedance and small-signal bandwidth of operational amplifier (op amp) models. In ...
A while back, I mentioned 1 that we needed a clean test fixture to measure an operational amplifier's input current in the low femtoampere region. But aside from a neat little integrating capacitor ...
In a simplified schematic from its datasheet, Linear Technology's LTC6268 (and 6269 dual) provide no evidence of "secret sauce." Rather, it shows a combination of semiconductor design and process ...
Measuring this one vital parameter (Input Offset Voltage) provides a simple means of determining if the DUT (Device Under Test) is either good or bad. The circuit is very simple, requiring only four ...
Semiconductor chips have been evolving to meet the demands of rapidly transforming applications, and so has the test technology to meet the test goals of those chips. Going back two decades or so, the ...
