Abstract

The theory of small signal linear junction transistor amplifiers is extended to develop design techniques which can be applied to the non-linear problems of switching circuit design. Many of these techniques differ materially from the corresponding techniques of vacuum tube amplifier design.

The linear theory is oriented toward the study of moderate-gain wide-band amplifiers driving non-inductive loads and being driven from non-inductive sources since switching circuit amplifiers commonly fall into this category, but many of the concepts have application to other amplifiers as well.

As outgrowth of the linear theory, the transistor parameters which are important in flip-flop operation are discussed, and a new way to measure these parameters is described.

The general theory of flip-flop design is discussed in some details and design data is presented for the most useful of the basic flip-flop circuits. Flip-flops were designed by the method presented here and their measured performance compared with the predicted performance. The generally good agreement between theory and experiment is taken as verification of the usefulness of both the design data and the basic concepts used in the derivation of the design data.

It is concluded from this study that junction transistors are practical switching circuit elements, and it is confidently predicted that they will eventually see wide use.
