In many systems, transmission lines drive reactive (mostly capacitive) loads. To preserve signal integrity, you should properly terminate the lines. However, the input impedance of CMOS logic ICs, for ...
Impedance matching is easy if you know the basics. Download the eBook to find out how. During impedance matching, a specific electronic load (R L) is made to match a generator output impedance (R g) ...
The recent EDN article of Bruce Trump () on the input impedance of an op-amp circuit took into account the single-pole roll-off of its loop gain. He showed with a simple derivation how the equivalent ...
