Modern op amps in old school designs
May 15, 2018
The output impedance of an op amp can have a profound impact on the overall circuit performance, but it is often overlooked in design. Newer design techniques have also resulted in some highly non-ideal characteristics for output impedance, and this can pose additional challenges when it comes to designing parts that exhibit these characteristics. This presentation introduces the concept of output impedance, the difference between open and closed loop, and how to verify if your model accurately captures this parameter.
