THE USE OF CONDUCTANCE CURVES FOR PENTODE CIRCUIT DESIGN.
Abstract
It is shown that a revised form of characteristics curves for pentode tubes offers a convenient method of circuit design. Contrary to the usual curves, this design may be carried out at any desired screen voltage, and small signal voltage amplification may be computed at the various bias values. A typical set of these curves is shown. A brief discussion of the transconductance (G curve) method of solution of circuits as applied to triodes is included, along with a statement of the most useful equations. Sources for equations for more complex circuits are listed. Typical design methods are indicated to show the usefulness of the technique. Techniques of choice of operating conditions with the use of the new curves, and methods of making first order corrections are indicated. The mode of attack in the design of a pentode oscillator to get desired operating characteristics is also indicated. A list of some of the circuit types which have been analyzed by this method is included. (Author)
