Abstract :
In the standard bipolar receiver amplifier configuration of a cascode stage followed by an emitter follower, inclusion of an inductor in series with the collector resistor is shown to give an improvement in the noise and bandwidth performance over that of the unmodified circuit. The bandwidth improvement is of the order of a factor of two. The predictions are confirmed by step response measurements
