HIGH SPEED OP AMPS
Walt Jung and Walt Kester
Modern system design increasingly makes use of high speed ICs as circuit building
blocks. With bandwidths going up and up, demands are placed on the designer for
faster and more power efficient circuits. The default high speed amplifier has
changed over the years, with high speed complementary bipolar (CB) process ICs
such as the AD846 and AD847 in use just about ten years at this writing. During
this time, the general utility/availability of these and other ICs have raised the “high
speed” common performance denominator to 50MHz. The most recent extended
frequency complementary b
