A generalized theory of transistor bias circuits
Transactions of the American Institute of Electrical Engineers, Part I: Communication and Electronics, 1958ONE of the important problems met in the design of transistor circuits is how to arrange the bias network to obtain the proper operating point and how to maintain this condition within specified limits, subject to environmental changes such as temperature, or to a range of parameters due to production spread in device manufacture. Several bias circuits

A general transformation with applications to circuit theory
Journal of the Franklin Institute, 1968Abstract A general functional transformation is introduced and some applications to circuit theory are given. The transformation is most useful in the area of active, nonbilateral circuits. This functional transformation introduces new voltages and currents which are linear combinations of the original voltages and currents plus their derivatives ...

Elements of general theory of null-balance circuits
1998 Midwest Symposium on Circuits and Systems (Cat. No. 98CB36268), 2002The null-balance method of output indication is widely used in instrumentation techniques and sensor applications. Yet, the theorems and methods of general circuit theory that are the basis of the null-circuit analysis and design have nearly disappeared from the modern books on network theory.

A generalized equivalent circuit in the theory of polyphase commutator motors
Electrical Engineering, 1941The demand for speed variation and power-factor compensation in a-c motors led to the development of the polyphase commutator types. In their simplest form these motors consist of two windings; a stator winding which is identical with that of the polyphase induction motor and a rotor winding of the closed type provided with a commutator and similar to ...

We generalize Kirchoff’s law for multiply connected wire networks to finite frequencies. We focus on the boundary conditions not present in the conventional Kirchoff’s law at joints when more than three wires come together, which is absent in our previous “circuit theory” for the finite frequency properties of metallic wire networks for singly ...

Notice of Retraction: Analysis of Loss Compensation on Generation Rights Trade by Circuit Theory
2010 Asia-Pacific Power and Energy Engineering Conference, 2010The generation rights trade could make the losses change, which should be compensated by the trade participants, so the fair loss compensation principle should be established, it could not only help for confirming the traders' responsibilities, but also help the generation rights trade to develop very quickly. This paper thinks that the key of solution

Triboelectric-generator-driven pulse electrodeposition for micropatterning.
Nano letters (Print), 2012By converting ambient energy into electricity, energy harvesting is capable of at least offsetting, or even replacing, the reliance of small portable electronics on traditional power supplies, such as batteries.
