TRANSISTORIZED LINEAR PULSE AMPLIFIERS
The basic investigation of transistor feedback amplifiers has proven mathematically simple and of great practical value. The behavior of single- stage commonemitier amplifiers is described and provides a building block with which cascaded feedback amplifiers can be analyzed and designed. From the results of this analysis the conditions for minimum drift for cascaded singlestages and cascaded loops have been derived. A transistorized linear amplifier, pulse-height discriminator, scaler, and high-voltage power supply packaged together is a single piece of portable counting gear is under development. The high-gain linear amplifier is the heart of the system and must have good reliability, wide bandwidth, small temperature-drift effects, etc. The amplifier developed has a rise time of 0.5 mu sec and current gain of 7,000, amd is designed to drive a currentpulse discriminator so that only a few volts swing at the output are needed.
