The use of a bulk photoconductor as a detector for microwave-modulated light or as a mixer to detect the beat frequency between coherent optical sources is studied. A model for the photoconductor as a parametric conductance is presented and used in the analysis of a dc-biased detector and an ac-biased mixer-detector arrangement. The results of experimental measurements on both dc- and ac-biased de... View full abstract»

A simple method of estimating delay in a switching network is outlined. The simplicity of formulas thus obtained makes them readily applicable for circuit comparisons or device optimization purposes. It is shown that a term involving the product of base resistance and diffusion capacitance forms a major limitation on high-speed, voltage-driven circuits. This method is applicable to a general class... View full abstract»

The critical parameters important to the design of an instantly operational cathode (0.1 sec heating time) for use in power tubes are discussed. Design information showing material selection, mechanical considerations, solution to lineal expansion problems, and methods of assisted heating are covered. The treatment of the cathode heating problem is presented in semi-normalized terms to make it mor... View full abstract»

By use of the finite-difference method of numerical analysis, a detailed numerical solution is obtained for the complete one-dimensional continuity equation, to study the transient and steady-state behavior of p-n junction diodes at moderate-to-high injection levels. The solution of the continuity equation is obtained for minority carriers in the base of a diode under the influence of drift, diffu... View full abstract»
