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 ...
Figure 1. Use the circuit in (a) to measure input bias current on the op amp’s noninverting input. Adding a loop amplifier in (b) keeps the op-amp stable for measurements on the inverting input. The ...
A tough challenge for test engineers is explored in terms of test methods, pitfalls, and measurement errors. For the test engineer, RF and microwave power amplifier testing imposes unique challenges.
More often than not we see folks on our forums and other forum websites debating how powerful a particular amplifier or receiver is based upon a single test popularized by many print magazines and ...
