A wideband operational amplifier with two selectable input stages
T.R. Anderson · 2003
Circuit design and measured performance are described for an operational amplifier with two selectable input stages, fabricated on an analog array chip. Gain bandwidth product is 2.4 GHz, channel switching time is approximately 5 ns. The circuit was developed for specific hybrid applications and then optimized for general-purpose use as a multiplexer, or virtually any other circuit function that might be implemented with an operational amplifier.>
