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 ...
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 ...
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 ...
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 ...
