Santa Clara, Calif. – Two chip makers are putting new process technologies to work in building operational amplifiers. National Semiconductor Corp. says its complementary bipolar process, implemented ...

Input crossover distortion has long been the bane of rail-to-rail op amps. The input stage for most R-R amps consists of p-and n-channel differential pairs (Fig. 1a). The result ...

The HF2LI (high-frequency, two inputs) from Zurich Instruments is a digital lock-in amplifier spanning the frequency ranging from DC to 50 MHz. The instrument has two physical input channels so that ...

I’m not sure why there’s such a dip in the middle. I verified both the RF generator and Vectawave amplifier outputs were flat, so it must have been the antenna or reflections in test setup. In any ...

10-MHz Op Amp Delivers High Output Drive. Oct. 8, 2008. ... operates from a single 2.7V to 5.5V supply and can swing to within 100 mV from the rails while sinking or sourcing 50 mA of output current.
