Stagger-Tuned Transistor Video Amplifiers

A method of analyzing common-emitter transistor video amplifiers has been given that is sufficiently simple and accurate for design work. This paper discusses the use of the above design method for the purpose of obtaining RC-coupled stagger-tuned video amplifiers. For a poles-canceling-zeros scheme, the design equations are given relating external circuit parameters to desired response shape and transistor parameters. By means of stagger tuning, the gain-times-bandwidth factor of a transistor amplifier is kept at unity as in the case of stagger-tuned vacuum tube amplifiers. Experimental results are given for amplifiers that are designed to be maximally flat by this method.
