Abstract :
The relative performance of a hierarchy of broadband amplifier designs is examined. This design hierarchy consists of an emitter-coupled pair with resistive-shunt loading for baseline comparison, a compound-device amplifier, a compensated series-feedback amplifier, and an actively shunt-peaked amplifier. Both pole-zero compensated amplifiers incorporate compound devices. The circuits are fabricated on Tektronix Inc.´s analog array chip featuring the SH3 process with 6.5 fT transistors
