Considerations in the Design of Transistor Luminance Output Amplifiers

The use of an emitter peaked transistor amplifier to provide luminance drive to the cathodes of a large screen color CRT is considered. The linear, small signal characteristics of emitter peaking are analyzed using pole-zero techniques. This theory is then checked by comparing numerical calculations to experimental measurements. The theoretical results in conjunction with certain practical considerations are then used to develop a useful design procedure. This is accompanied by a sample design. Collector peaking circuits are well documented in the literature and will not be discussed in this paper.
